Nonlinear Conjugate Gradient Methods in Micromagnetics

open access: yesAIP Advances, 2017
Conjugate gradient methods for energy minimization in micromagnetics are compared. The comparison of analytic results with numerical simulation shows that standard conjugate gradient method may fail to produce correct results. A method that restricts the

Experimental approaches for micromagnetic coercivity analysis of advanced permanent magnet materials

open access: yesScience and Technology of Advanced Materials, 2021
Although coercivity is one of the fundamental properties of permanent magnets, it has not been well understood. In this paper, micromagnetics and thermal activation magnetization reversal theories are briefly reviewed, and then our recent macroscopic and

Self-Reset Schemes for Magnetic Domain Wall-Based Neuron

open access: yesIEEE Journal on Exploratory Solid-State Computational Devices and Circuits, 2022
Spintronic artificial spiking neurons are promising due to their ability to closely mimic the leaky integrate-and-fire (LIF) dynamics of the biological LIF spiking neuron. However, the neuron needs to be reset after firing.
