Skyrmion-Induced Memristive Magnetic Tunnel Junction for Ternary Neural Network

IEEE Journal of the Electron Devices Society, 2019
Novel skyrmion-magnetic tunnel junction (SK-MTJ) devices were investigated for the first time to implement the ternary neural networks (TNN). In the SK-MTJ, an extra magnetoresistance state beyond binary parallel and anti-parallel MTJ states was achieved

Generation and Enhancement of Persistent Nanoscale Magnetization in All‐Dielectric Metasurfaces by Optically Injected and Localized Free Carriers

Advanced Science, EarlyView.
Infrared metasurface‐guided waves (IR‐MGW) scattered by a time interface (TI) induced by rapid, localized free‐carrier generation can be efficiently rectified to generate strong, persistent magnetic fields. We develop a rigorous, theoretical model to study a time‐varying, dispersive medium and uncover the redistribution of the initial energy of the IR ...

Shapiro like steps reveals molecular nanomagnets’ spin dynamics

AIP Advances, 2015
We present an accurate way to detect spin dynamics of a nutating molecular nanomagnet by inserting it in a tunnel Josephson junction and studying the current voltage (I-V) characteristic.

Anomalous switching in submicrometer magnetic tunnel junction arrays arising from magnetic vortex and domain wall pinning

, 2004
We present switching characteristics of patterned submicrometer magnetic tunnel junction arrays containing NiFe and CoFe free layers. The resemblance of magnetization and magnetoresistance (MR) curves was studied by micromagnetic calculations and ...

Integration of Reconfigurable p‐Bit and 1R Crossbar Array for Memristive Probabilistic Computing

Advanced Science, EarlyView.
A memristive probabilistic computing system is demonstrated by integrating stochastic p‐bits based on volatile memristors with a 1R crossbar array encoding interaction weights. The system performs weighted‐sum operations across the array and updates p‐bits iteratively.

Spin transfer torque driven higher-order propagating spin waves in nano-contact magnetic tunnel junctions

Nature Communications, 2018
Nano-contact-based spin wave generation may enable high-frequency magnonic devices but has been limited to long wavelengths and weak signal strengths.

NbOx Mott Memristor‐Based Oscillatory P‐trit for Ternary Potts Machine

Advanced Science, EarlyView.
A ternary Potts machine utilizing NbOx‐based probabilistic trits (p‐trits) is demonstrated for efficient combinatorial optimization. By leveraging the electro‐thermal switching dynamics of NbOx memristors, this architecture generates three‐state stochastic fluctuations.
