TANMS is proud to recognize TANMS Graduate Student, Qianchang Wang, for winning Best Poster Award at the 2018 IEEE International Magnetics Conference in Signapore. Qianchang is a fourth year Ph.D. candidate under Professor Gregory Carman in the UCLA Department of Mechanical and Aerospace Engineering. Her research focuses on modeling multiferroic systems coupled with spin-orbit torque using finite element method, with applications in magnetic memory and logic.  This work numerically demonstrates the ultra energy efficiency of multiferroic control of a nanoscale magnetic memory bit. The energy consumption is as low as 22 aJ per flip for a Terfenol-D disk, which is 3-4 orders more energy efficient than current-based control mechanisms.

Voltage Induced Strain-mediated Perpendicular Magnetization Control for In-memory Computing Device

ABSTRACT: Magnetic memory has attracted substantial attention due to its promise of high energy efficiency combined with non-volatility. Conventionally, the magnetization is controlled by spin-transfer torque (STT) current but ohmic heating makes the current-based switching mechanisms energy inefficient (100fJ/flip). In contrast, strain-mediated multiferroic composites (i.e. coupled magnetoelastic and piezoelectric thin films) provide ultra-high energy efficiency as high as 100aJ/flip due to negligible induced current during the switching process.  In this study, a fully coupled model is used to simulate strain-mediated magnetization control of nanodots with perpendicular magnetic anisotropy (PMA) on a PZT (Pby[ZrxTi1-x]O3) thin film. This model is also used to study Bennet clocking of nanodot arrays.

TANMS is proud to recognize TANMS Graduate Student, Zhi (Jackie) Yao, for winning the Best Student Paper Competition at the 2017 IEEE International Microwave Symposium in Hawaii.  Jackie is a fifth year Ph.D. candidate under Professor Ethan Wang in the UCLA Department of Electrical Engineering.  Her research focuses on the development of 3D multiferroic antenna modeling capability that incorporates full interactions between elastodunamics, micromagnetics and electromagnetics. The TANMS 3D antenna modeling is a rigorous yet computationally efficient, and capable of modeling the complex magnetoelastic anisotropies, dispersive, and/or nonlinear behavior accurately. The numerical modeling tool provides guidelines and theoretical support to the multiferroic antenna design which is progressing along well within the center. 

[The following is the title/abstract of the paper that was presented at the 2017 IEEE Conference]

3D Unconditionally Stable FDTD Modeling of Micromagnetics and Electrodynamics

ABSTRACT: A rigorous yet computationally efficient three-dimensional numerical method has been proposed based on modified alternating-direction-implicit (ADI) finite difference time domain methods (FDTD) and it has the capability of modeling the eccentric property of magnetic material being anisotropic, dispersive or nonlinear. The proposed algorithm solves Maxwell’s equations and LLG equations simultaneously, requiring only tridiagonal matrix inversion as in ADI FDTD. The accuracy of the modeling has been validated by the simulated dispersive permeability of a continuous ferrite film with a 1.5 mm-thickness, using a time-step size 104times larger than the Courant limit. The permeability agrees with the theoretical prediction and magneto-static spin wave modes are observed. Moreover, electric current sheet radiators close to perfect electrical conductors loaded with 2 mm-thick ferrite films are simulated, which exhibit a radiation efficiency boost-up due to elimination of platform effect.


TANMS Successfully Pilots New High School Outreach Program and Welcomes Lawndale High School as a New Precollege Partner

posted Jun 1, 2017, 2:29 PM by Tsai-Tsai O-Lee   [ updated Jun 1, 2017, 5:07 PM ]

TANMS just welcomed 200 high school students from Lawndale High School in Centinela Valley High School District into our extended family!  For four days during this last week of May, TANMS graduate students, Kevin Fitzell, Maggie Xiao, Cai Chen, and Stephen Sasaki collaborated and team-taught the brand-new TANMS Electromagnetism and Nanoscale Motor Modules that they co-developed with physics teacher, Maria Lyn Genota, as part of the new TANMS high school outreach initiative that has been almost one year in the making.  The enthusiasm and dedication from Ms. Genota and these full-time graduate researchers have been astounding and was the invaluable driving force behind the successful implementation of this program.

Ms. Genota came to TANMS as a participant of our 2016 Research Experience for Teachers (RET) program with high recommendations from Lawndale High School principal, Paula Rodas, and UCLA MESA/CEED Director, Rick Ainsworth.  Widely recognized for her outstanding and dedicated teaching, Ms. Genota is a recipient of numerous awards including Teacher of the Year from Inglewood Unified School District in 2016, MESA Advisor of the Year for the State of California in 2007, and the Certificated Employee of the Year from Lawndale High School in 2017.  As TANMS Deputy Director, Professor Jane Chang, so well indicated, “TANMS is truly fortunate to have Ms. Genota whose dedicated effort makes it possible to broaden the impact of our ERC.”

The TANMS Electromagnetism and Nanoscale Motor Modules were developed to align with the Next Generation Science Standards (NGSS) while incorporating fundamental concepts from core TANMS research involving multiferroics and nanoscale motors.  Over two class periods, students engage in interactive lectures and hands-on activities as they investigate the world electromagnetism and explore multiferroic science and nanomotors.

The four-day pilot implementation at Lawndale High School culminated with a closing ceremony where all of the students who participated gathered to be recognized for their contribution to the new TANMS effort.  Members of the TANMS leadership team also provided inspirational talks that invited the students to explore their potentials as future engineers. 

We are extremely excited to witness the success of the Lawndale High School pilot.  In just a few weeks on June 22-24, TANMS will be hosting the first TANMS Summer Teacher Institute at UCLA.  In partnership with UCLA Center forExcellence in Engineering Diversity, UCLA MESA, and UCLA Science Project, TANMS will introduce the new TANMS Electromagnetism and Nanoscale Motor Module along with NGSS and Common Core strategies to a group of MESA teachers from the Los Angeles region.  Together, we aim to broaden our impact in encouraging the pursuit of STEM from high school and beyond.

Students show off winnings from hard-earned raffle tickets!
