TANMS to Welcome Two TANMS Doctoral Fellowship Recipients

posted Apr 24, 2017, 4:00 PM by Tsai-Tsai O-Lee   [ updated Apr 24, 2017, 4:15 PM ]

Of the four TANMS Doctoral Fellowship awards that were offered this year, TANMS is excited and proud to announce that two incoming doctoral students, Adrian Acosta and Michael Guevara de Jesus, have accepted the awards and will be joining the TANMS research team in fall 2017. The TANMS Doctoral Fellowship was established to encourage students from underrepresented groups to pursue a doctoral degree in Engineering with a focus on TANMS research to advance diversity and innovation in the field. Graduating from the Interamerican University of Puerto Rico with a degree in Mechanical Engineering, Michael Guevara de Jesus is not new to the TANMS family.  Michael first joined the TANMS family in summer 2014 as a participant of the Research Experience for Undergraduates (REU) program under the late Professor Ephraphim Garcia at Cornell University.  He returned to TANMS for a second summer of REU in 2016 under Professor Abdon Sepulveda at UCLA.  Michael will conduct his doctoral research under the supervision of Professor Christopher Lynch in UCLA Department of Mechanical and Aerospace Engineering.  Adrian Acosta comes to TANMS with the highest recommendations from the University of Arizona with a degree in Chemical Engineering.  He will be joining the TANMS team under Professor Jane Chang in UCLA Chemical and Biomolecular Engineering.  We are fortunate to have them both on board and offer our most hearty Congratulations and Welcome!

TANMS Doctoral Student Receives Tenure-Track Faculty Appointment

posted Apr 24, 2017, 9:37 AM by Michelle Schwartz   [ updated Apr 24, 2017, 11:18 AM ]

TANMS is very proud to announce that one of our doctor students, John Domann, was offered a tenure-track faculty position at Virginia Tech.  John will serve as an Assistant Professor in the Biomedical Engineering and Mechanics (BEAM) Department at Virginia Tech starting in the next academic year. John is currently finishing his Ph.D. in the Active Materials Laboratory under Professor Greg Carman with UCLA Mechanical and Aerospace Engineering. John received his bachelor’s and master’s degress from the University of Kansas, where he was named a Fellow with the Institute for Advancing Medical Innovation and co-invented a piezoelectric spinal fusion implant that recently finished a successful animal trial and has been licensed by a startup company.

John’s doctoral work at UCLA broadly focused on the dynamics of magnetoelastic materials across numerous size and time scales. He worked with AFRL researchers from Eglin Air Force Base to conduct experimental studies on the impact and shock response of Galfenol, a magnetoelastic material. This work included analysis of Galfenol’s use in pulsed power generation devices, as well as the first analytic model of a strain-powered antenna. John’s recent work with TANMS focused on the strain mediated control of nanoscale magnetism. The goal of this work is to create novel devices with multiple orders of magnitude energy efficiency improvements of current state of the art electronics. He collaborated with numerous TANMS researchers to explore the magnetoelastic control of the quantum mechanical exchange bias effect, energy efficient magnetic logic devices, novel antenna designs, and micron scale magnetic motors. In addition to his research, John made significant contributions to the TANMS Education programs by serving as a graduate mentor and by participating in the development of teaching modules that introduced high school and undergraduate students to multiferroic materials and devices.  John looks forward to continuing his research on multiferroic devices and exploring their applications in the biomedical field at Virginia Tech.

TANMS Industry Member Inston Inc. Receives NSF Small Business/ERC Collaboration Opportunity Award

posted Mar 30, 2017, 8:17 AM by Michelle Schwartz   [ updated Mar 30, 2017, 9:15 AM by Tsai-Tsai O-Lee ]

We are happy to announce that one of our Industrial Affiliates members, Inston Inc., was recently (February 2017) awarded a NSF SECO grant.

TANMS collaborated with INSTON to submit a SECO (Small-Business/ ERC Collaborative Opportunity) Supplemental Funding Opportunity available to current NSF SBIR Phase 2 awardees that collaborate with current NSF ERCs.  Award details and abstract is available at .

Working with TANMS under this SECO supplement, Inston plans to achieve ambitious memory device metrics that go beyond those originally outlined in its Phase II program, to support its technical roadmap for the 20 nm CMOS technology node and beyond. Inston plans to achieve this by leveraging the joint expertise at Inston and TANMS. In particular, the expertise and facilities available within TANMS with respect to strain engineering of nanomagnetic devices – both modeling and experimental – will significantly accelerate Inston’s progress to achieve this technology milestone.

This partnership will make MeRAM devices compatible with CMOS 20 nm and below nodes without the need for high-voltage transistors or charge pumping, hence achieving higher-density memory arrays. Based on Inston’s interactions with customers and semiconductor foundries, it sees a large opportunity at these technology nodes for MeRAM to replace high-performance embedded SRAM.  In particular, while recent public announcements from foundries (Samsung and Global Foundries) have confirmed that magnetic memory will be available within two years at the 28 nm node, there is a pressing need to develop solutions for the 20 nm node and below, as well as to achieve higher speed to replace SRAM (currently not possible with spin torque MRAM, which is too slow compared to SRAM Cache memories). This is driven by the scaling challenges of current-controlled spin-torque MRAM to achieve competitive performance at 20 nm and below nodes, where our voltage-controlled MeRAM offers a clear performance-density advantage.

We are looking forward to collaborating with Inston Inc on this exciting NSF SECO!

"Ultrafast and Very Small: Discover Nanoscale Magnetism With Picosecond Time Resolution Using X-Rays" 
by Hendrik Ohldag, 2017 Distinguished Lecturer/SLAC

February 24, 2017 | 10:00am-11:00am PST
TANMS Conference Room | WebEx (Meeting Password: TANMS)


Today’s magnetic device technology is based on complex magnetic alloys or multilayers that are patterned at the nanoscale and operate at gigahertz frequencies. To better understand the behavior of such devices one needs an experimental approach that is capable of detecting magnetization with nanometer and picosecond sensitivity. In addition, since devices contain different magnetic elements, a technique is needed that provides element-specific information about not only ferromagnetic but antiferromagnetic materials as well. Synchrotron based X-ray microscopy provides exactly these capabilities because a synchrotron produces tunable and fully polarized X-rays with energies between several tens of electron volts up to tens of kiloelectron volts. The interaction of tunable X-rays with matter is element-specific, allowing us to separately address different elements in a device. The polarization dependence or dichroism of the X-ray interaction provides a path to measure a ferromagnetic moment and its orientation or determine the orientation of the spin axis in an antiferromagnet. The wavelength of X-rays is on the order of nanometers, which enables microscopy with nanometer spatial resolution. And finally, a synchrotron is a pulsed X-ray source, with a pulse length of tens of picoseconds, which enables us to study magnetization dynamics with a time resolution given by the X-ray pulse length in a pump-probe fashion. The goal of this talk is to present an introduction to the field and explain the capabilities of synchrotron based X-ray microscopy, which is becoming a tool available at every synchrotron, to a diverse audience. The general introduction will be followed by a set of examples, depending on the audience, that may include properties of magnetic materials in rocks and meteorites, magnetic inclusions in magnetic oxides, interfacial magnetism in magnetic multilayers, and dynamics of nanostructured devices due to field and current pulses and microwave excitations.


Hendrik Ohldag received the Ph.D. in experimental physics from the Universität Düsseldorf, Germany, in 2002. He joined the Stanford Synchrotron Radiation Light Source (SSRL) in 1999 as a research assistant as part of his Ph.D. research. After a postdoctoral fellowship at SSRL he became a permanent member of the research staff in 2005. Between 1999 and 2002 he was a visiting researcher at the Advanced Light Source (ALS) at Berkeley National Laboratory. Since 2014 he is a visiting researcher at New York University.
Dr. Ohldag was awarded the David. A Shirley Award at the ALS in 2006 for “outstanding contribution in using photoemission electron microscopy for the study of magnetic materials.” He is a member of the IEEE Magnetics Society and the chair of the Magnetic Interfaces and Nanoscale Device Division of the American Vacuum Society. He has authored or co-authored over 50 peer-reviewed papers and book chapters which have been cited over 2500 times. He has participated in the organization of 25 international conferences and workshops. His research focuses on the use of X-ray microscopy to study the dynamic and static properties of complex magnetic materials.

Electrical switching of an antiferromagnet
Louis Néel pointed out in his Nobel lecture that while abundant and interesting from theoretical viewpoint, antiferromagnets did not seem to have any applications. Indeed, the alternating directions of magnetic moments on individual atoms and the resulting zero net magnetization make antiferromagnets hard to control by tools common in ferromagnets. Strong coupling would be achieved if the externally generated field had a sign alternating on the scale of a lattice constant at which moments alternate in antiferromagnets. However, generating such a field has been regarded unfeasible, hindering the research and applications of these abundant magnetic materials. Theoreticians have recently predicted that relativistic quantum mechanics may offer staggered current induced fields with the sign alternating within the magnetic unit cell which can facilitate a reversible switching of an antiferromagnet by applying electrical currents with comparable efficiency to ferromagnets. Among suitable materials is a high Néel temperature antiferromagnet, tetragonal-phase CuMnAs, which we have recently synthesized in the form of single-crystal epilayers structurally compatible with common semiconductors. We demonstrate electrical writing and read-out, combined with the insensitivity to magnetic field perturbations, in a proof-of-concept antiferromagnetic memory device which operates USB-powered at room temperature.

Publishing invoices using spintronics

While I was a student and a post-doc, I got the feeling that spintronics was limited to data storage and random access memories. And so I was preparing my applications to start my senior academic career in 2013. I was aware that magnetic sensors had numerous applications but to some extend there was not enough “new research” to be done as to justify starting a new academic group. In this talk, I will walk through the business activities I took part in the past 3 years by which I fund some of my subsequent personal scientific research in spintronics using a couple of successful applications of magnetic sensors. 

A majority of scientists have a natural skill for managing large data sets, modelling and connecting the dots. In this talk, I will discuss the additional ingredients needed to turn this “mental integration ability and creativity” of scientists into invoices - the key paper. One often forgotten and misunderstood ingredient is the internet. It brings a tremendous additional value to any gadget simply because it is connected: One dollar becomes ten dollars, if the data flows properly into an iPad. 

On a more general frame, I will discuss how such small start-ups can be a feasible path to partially fund fundamental academic research. Scientific groups and its concomitant technology transfer departments operate nowadays in an imposed short-termism and, eventually, short-budgetism. For instance, It is very hard to achieve a significant success in revolutionizing the magnetic data storage market when, on one side, standard cycles are limited to 3~5 years and budgets to 1~5 million while the target is to attract the attention of 30 year old multinational companies. We will discuss several strategies that I have witnessed to tackle these challenges and I would like to brainstorm briefly on alternative paths and, specially, those ones which UCLA is currently following.
