Spin-orbit torque characterization in a nutshell
Minh-Hai Nguyen, Chi-Feng Pai
Spin current and spin torque generation through the spin-orbit interactions in solids, of bulk or interfacial origin, is at the heart of spintronics research. The realization of sp…
Reservoir Computing with Superconducting Electronics
Graham E. Rowlands, Minh-Hai Nguyen, Guilhem J. Ribeill +5
The rapidity and low power consumption of superconducting electronics makes them an ideal substrate for physical reservoir computing, which commandeers the computational power inhe…
Symmetry-Aware Reservoir Computing
Wendson A. S. Barbosa, Aaron Griffith, Graham E. Rowlands +5
We demonstrate that matching the symmetry properties of a reservoir computer (RC) to the data being processed dramatically increases its processing power. We apply our method to th…
Nanosecond Reversal of Three-Terminal Spin Hall Effect Memories Sustained at Cryogenic Temperatures
Graham E. Rowlands, Minh-Hai Nguyen, Sriharsha V. Aradhya +4
We characterize the nanosecond pulse switching performance of the three-terminal magnetic tunnel junctions (MTJs), driven by the spin Hall effect (SHE) in the channel, at a cryogen…
Cryogenic Memory Architecture Integrating Spin Hall Effect based Magnetic Memory and Superconductive Cryotron Devices
Minh-Hai Nguyen, Guilhem J. Ribeill, Martin Gustafsson +19
One of the most challenging obstacles to realizing exascale computing is minimizing the energy consumption of L2 cache, main memory, and interconnects to that memory. For promising…
Efficient Switching of 3-Terminal Magnetic Tunnel Junctions by the Giant Spin Hall Effect of Alloy
Minh-Hai Nguyen, Shengjie Shi, Graham E. Rowlands +4
Recent research has indicated that introducing impurities that increase the resistivity of Pt can enhance the efficiency of the spin Hall torque it generates. Here we directly demo…
Spin torque study of the spin Hall conductivity and spin diffusion length in platinum thin films with varying resistivity
Minh-Hai Nguyen, D. C. Ralph, R. A. Buhrman
We report measurements of the spin torque efficiencies in perpendicularly-magnetized Pt/Co bilayers where the Pt resistivity is strongly dependent on thickness .…
Enhancement of the Anti-Damping Spin Torque Efficacy of Platinum by Interface Modification
Minh-Hai Nguyen, Chi-Feng Pai, Kayla X. Nguyen +3
We report a strong enhancement of the efficacy of the spin Hall effect (SHE) of Pt for exerting anti-damping spin torque on an adjacent ferromagnetic layer by the insertion of $\ap…
Enhancement of Perpendicular Magnetic Anisotropy and Transmission of Spin-Hall-Effect-Induced Spin Currents by a Hf Spacer Layer in W/Hf/CoFeB/MgO Layer
Chi-Feng Pai, Minh-Hai Nguyen, Carina Belvin +3
We report that strong perpendicular magnetic anisotropy of the ferromagnetic layer in a W/CoFeB/MgO multilayer structure can be established by inserting a Hf layer as thin as 0.25…
Phase Transition to Insulating State from Quantum Hall State by Current-Induced Nuclear Spin Polarization
Shibun Tsuda, Minh-Hai Nguyen, Daiju Terasawa +2
We investigate the resistance enhancement state (RES) where the magnetoresistance of the fractional quantum Hall state (FQHS) is increased with dynamic nuclear spin polari…
Interlayer Diffusion of Nuclear Spin Polarization in Quantum Hall States
Minh-Hai Nguyen, Shibun Tsuda, Daiju Terasawa +3
At the spin transition point of quantum Hall states, nuclear spins in a two-dimensional electron gas are polarized by an electric current. Using GaAs/AlGaAs double-quantum-…
