Rectifiability of entropy defect measures in a micromagnetics model [PDF]

open access: yesAdvances in Calculus of Variations, 2020
We study the fine properties of a class of weak solutions u of the eikonal equation arising as asymptotic domain of a family of energy functionals introduced in [T. Rivière and S.

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.

Second-order semi-implicit projection methods for micromagnetics simulations [PDF]

open access: yesJournal of Computational Physics, 2019
Micromagnetics simulations require accurate approximation of the magnetization dynamics described by the Landau-Lifshitz-Gilbert equation, which is nonlinear, nonlocal, and has a non-convex constraint, posing interesting challenges in developing ...

Dependence of Nonlinear Response and Magnon Scattering on Damping

open access: yesIEEE Journal of Microwaves, 2021
A previous theoretical model of 3-magnon scattering is connected to experimentally measured characteristics, such as the damping constant α and the power threshold, through a realistic micromagnetic simulation.

Hysteresis of Natural Magnetite Ensembles: Micromagnetics of Silicate‐Hosted Magnetite Inclusions Based on Focused‐Ion‐Beam Nanotomography

open access: yesGeochemistry Geophysics Geosystems, 2020
Three‐dimensional geometries of silicate‐hosted magnetic inclusions from the Harcus intrusion, South Australia have been determined using focused‐ion‐beam nanotomography (FIB‐nt). By developing an effective workflow, the geometries were reconstructed for

On a Sharp Poincaré-Type Inequality on the 2-Sphere and its Application in Micromagnetics [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2019
The main aim of this note is to prove a sharp Poincar\'e-type inequality for vector-valued functions on $\mathbb{S}^2$, that naturally emerges in the context of micromagnetics of spherical thin films.

Micromagnetics of rare-earth efficient permanent magnets [PDF]

open access: yes, 2018
The development of permanent magnets containing less or no rare-earth elements is linked to profound knowledge of the coercivity mechanism. Prerequisites for a promising permanent magnet material are a high spontaneous magnetization and a sufficiently ...

Generic role of the Dzyaloshinskii–Moriya interaction in nanocrystalline ferromagnets

open access: yesNew Journal of Physics, 2023
Motivated by recent experimental polarized neutron results, we present a numerical micromagnetic study of the interfacial (intergrain) Dzyaloshinskii–Moriya interaction (DMI) in nanocrystalline terbium.

Finite Element Approach for the Simulation of Modern MRAM Devices

open access: yesMicromachines, 2023
Because of their nonvolatile nature and simple structure, the interest in MRAM devices has been steadily growing in recent years. Reliable simulation tools, capable of handling complex geometries composed of multiple materials, provide valuable help in ...
