Switching Characteristics of Electrically Connected Stochastically Actuated Magnetic Tunnel Junction Nanopillars
Dairong Chen, Ahmed Sidi El Valli, Jonathan Z. Sun +3
We investigate the stochastic dynamics of nanoscale perpendicular magnetic tunnel junctions (pMTJs) and the correlations that arise when they are electrically coupled. Individual j…
Tunable Random Telegraph Noise in Stable Perpendicular Magnetic Tunnel Junctions for Unconventional Computing
Ahmed Sidi El Valli, Michael Tsao, Dairong Chen +1
We demonstrate that thermally stable perpendicular magnetic tunnel junctions (pMTJs), widely used in spin-transfer torque magnetic random-access memory, can be actuated with nanose…
A Toffoli Gadget for Magnetic Tunnel Junctions Boltzmann Machines
Dairong Chen, Augustin Couton Wyporek, Pierre Chailloleau +6
Magnetic Tunnel Junctions (MTJs) are of great interest for non-conventional computing applications. The Toffoli gate is a universal reversible logic gate, enabling the construction…
Optimizing Hybrid Ferromagnetic Metal-Ferrimagnetic Insulator Spin-Hall Nano-Oscillators: A Micromagnetic Study
Robert Xi, Ya-An Lai, Andrew D. Kent
Spin-Hall nano-oscillators (SHNO) are nanoscale spintronic devices that generate high-frequency (GHz) microwave signals useful for various applications such as neuromorphic computi…
Solving combinatorial optimization problems through stochastic Landau-Lifshitz-Gilbert dynamical systems
Dairong Chen, Andrew D. Kent, Dries Sels +1
We present a method to approximately solve general instances of combinatorial optimization problems using the physical dynamics of 3d rotors obeying Landau-Lifshitz-Gilbert dynamic…
