Bridging femtosecond and picosecond magnetization dynamics: a multiscale framework for ultrafast demagnetization

Journal of Materials Chemistry C
A multiscale framework bridges coherent femtosecond electron dynamics (rt-TDDFT) and picosecond thermal spin dynamics (LLG/LLB) via Boltzmann + T-matrix modelling of nonthermal electron–magnon–phonon scattering during ultrafast demagnetization.

Dependence of Demagnetization Quality of Ferromagnetic Bodies on Frequency Relationship and Duration of Demagnetization Process

, 2007
Experiments have revealed that demagnetization quality of ferromagnetic bodies depends on characteristics of demagnetizing field that are determined by their size and internal properties.

Demagnetization factors and field of hemispherical objects

Demagnetization factors play an important role in micromagnetics modeling but exact solutions only exist for a limited number of particle shapes. Here we use a Fourier space based approach coupled to the concept of magnetic charges to derive analytically

Active Fault-tolerant Control for Surface Permanent Magnet Synchronous Motor Under Demagnetization Fault

This paper introduces a novel method for controlling a surface permanent magnet synchronous motor (SPMSM) during demagnetization fault conditions. The proposed fault-tolerant control (FTC) system incorporates a combination of a fuzzy extended state ...

High harmonic generation for the study of the demagnetization dynamics of cobalt films

, 2015
L’objectif de cette est de développer une source harmonique permettant de couvrir la gamme d’énergie 50 -70 eV du spectre électromagnétique par la génération d’harmoniques d’ordre élevé dans un gaz rare. Cette source appelée "tabletop" est obtenue à partir d’un système laser femtoseconde basé sur la technique d’amplification à dérive de fréquence.
