Solid-state transcapacitor, a new gain element for logic, memory and interconnects
Amrita Mathuriya, Roza Kotlyar, Neal Reynolds +9
Today's transistors dictate the voltage and charge scales for both logic and memory. While AI systems are recognized to be limited by memory energy, the dominant share of the energ…
Creation and confirmation of Hopfions in magnetic multilayer systems
N. Kent, N. Reynolds, D. Raftrey +11
Topological solitons have been studied for decades in classical field theories, and have started recently to impact condensed matter physics. Among those solitons, magnetic skyrmio…
Strong, Temperature-Dependent Spin-Orbit Torques in Heavy Fermion YbAl
Neal D Reynolds, Shouvik Chatterjee, Gregory M. Stiehl +6
The use of current-generated spin-orbit torques[1] to drive magnetization dynamics is under investigation to enable a new generation of non-volatile, low-power magnetic memory. Pre…
Current-Induced Torques with Dresselhaus Symmetry Due to Resistance Anisotropy in 2D Materials
Gregory M. Stiehl, David MacNeill, Nikhil Sivadas +7
We report measurements of current-induced torques in heterostructures of Permalloy (Py) with TaTe, a transition-metal dichalcogenide (TMD) material possessing low crystal symme…
Exceptionally high, strongly temperature dependent, spin Hall conductivity of SrRuO3
Yongxi Ou, Zhe Wang, Celesta S. Chang +7
Spin-orbit torques (SOT) in thin film heterostructures originate from strong spin-orbit interactions (SOI) that, in the bulk, generate a spin current as the result of extrinsic spi…
Anisotropic spin-orbit torque generation in epitaxial SrIrO3 by symmetry design
T. Nan, T. J. Anderson, J. Gibbons +13
Spin-orbit coupling (SOC), the interaction between the electron spin and the orbital angular momentum, can unlock rich phenomena at interfaces, in particular interconverting spin a…
Spin-orbit torques in NbSe/Permalloy bilayers
Marcos H. D. Guimaraes, Gregory M. Stiehl, David MacNeill +2
We present measurements of current-induced spin-orbit torques generated by NbSe, a fully-metallic transition-metal dichalcogenide material, made using the spin-torque ferromagn…
Thickness dependence of spin-orbit torques generated by WTe2
David MacNeill, Gregory M. Stiehl, Marcos H. D. Guimaraes +3
We study current-induced torques in WTe2/permalloy bilayers as a function of WTe2 thickness. We measure the torques using both second-harmonic Hall and spin-torque ferromagnetic re…
Increased low-temperature damping in yttrium iron garnet thin films
C. L. Jermain, S. V. Aradhya, J. T. Brangham +6
We report measurements of the frequency and temperature dependence of ferromagnetic resonance (FMR) for a 15-nm-thick yttrium iron garnet (YIG) film grown by off-axis sputtering. A…
Spin-Hall Torques Generated by Rare-Earth (Lanthanide) Thin Films
Neal Reynolds, Priyamvada Jadaun, John T. Heron +6
We report an initial experimental survey of spin-Hall torques generated by the rare-earth metals Gd, Dy, Ho, and Lu, along with comparisons to first-principles calculations of thei…
All-Optical Vector Measurement of Spin-Orbit-Induced Torques Using Both Polar and Quadratic Magneto-Optic Kerr Effects
Xin Fan, Alex R. Mellnik, Wenrui Wang +6
We demonstrate that the magneto-optic-Kerr effect with normal light incidence can be used to obtain quantitative optical measurements of both components of spin-orbit-induced torqu…
