Simulated annealing with time-varying strain in a dipole-coupled array of magnetostrictive nanomagnets
Md Ahsanul Abeed, Supriyo Bandyopadhyay
In a two-dimensional arrangement of closely spaced elliptical nanomagnets with in-plane magnetic anisotropy, whose major axes are aligned along columns and minor axes along rows, d…
Experimental Demonstration of an Extreme Sub-Wavelength Nanomagnetic Acoustic Antenna Actuated by Spin-Orbit Torque from a Heavy Metal Nanostrip
Md Ahsanul Abeed, Supriyo Bandyopadhyay
A novel on-chip extreme sub-wavelength "acoustic antenna" whose radiation efficiency is ~50 times larger than the theoretical limit for a resonantly driven antenna is demonstrated.…
A Nanomagnetic Voltage-Tunable Correlation Generator between Two Random Bit Streams for Stochastic Computing
M. T. McCray, Md Ahsanul Abeed, Supriyo Bandyopadhyay
Graphical probabilistic circuit models of stochastic computing are more powerful than the predominant deep learning models, but also have more demanding requirements. For example,…
Low Barrier Nanomagnet Design for Binary Stochastic Neurons: Design Challenges for Real Nanomagnets with Fabrication Defects
Md Ahsanul Abeed, Supriyo Bandyopadhyay
Much attention has been focused on the design of low barrier nanomagnets (LBM), whose magnetizations vary randomly in time owing to thermal noise, for use in binary stochastic neur…
Sensitivity of the Power Spectra of Magnetization Fluctuations in Low Barrier Nanomagnets to Barrier Height Modulation and Defects
Md Ahsanul Abeed, Supriyo Bandyopadhyay
Nanomagnets with small shape anisotropy energy barriers on the order of the thermal energy have unstable magnetization that fluctuates randomly in time. They have recently emerged…
Error Probability in Magneto-elastic Switching of Non-ideal Nanomagnets with Defects: A Case Study for the Viability of Straintronic Logic and Memory
David Winters, Md Ahsanul Abeed, Sourav Sahoo +2
Magneto-elastic (straintronic) switching of bistable magnetostrictive nanomagnets is an extremely energy-efficient switching methodology for (magnetic) binary switches that has rec…
A Microwave Oscillator Based on a Single Straintronic Magneto-tunneling Junction
Md Ahsanul Abeed, Justine L. Drobitch, Supriyo Bandyopadhyay
There is growing interest in exploring nanomagnetic devices as potential replacements for electronic devices (e.g. transistors) in digital switching circuits and systems. A special…
