Mode-resolved micromagnetics study of parametric spin wave excitation in thin-film disks [PDF]
Physical review BWe present a computational study of the parametric excitation of spin waves in thin film disks with a mode-resolved approach. The method involves projecting out the time-dependent magnetization, computed using micromagnetics simulations, onto the spatial

Computational micromagnetics with Commics [PDF]
Computer Physics Communications, 2020 We present our open-source Python module Commics for the study of the magnetization dynamics in ferromagnetic materials via micromagnetic simulations. It implements state-of-the-art unconditionally convergent finite element methods for the numerical integration of the Landau-Lifshitz-Gilbert equation.

Convergence of an implicit-explicit midpoint scheme for computational micromagnetics [PDF]
Computers and Mathematics with Applications, 2016 Based on lowest-order finite elements in space, we consider the numerical integration of the Landau–Lifschitz–Gilbert equation (LLG). The dynamics of LLG is driven by the so-called effective field which usually consists of the exchange field, the ...

Micromagnetics of anti-skyrmions in ultrathin films [PDF]
, 2017 We present a combined analytical and numerical micromagnetic study of the equilibrium energy, size and shape of anti-skyrmionic magnetic configurations. Anti-skyrmions can be stabilized when the Dzyaloshinskii-Moriya interaction has opposite signs along ...

Micromagnetics of curved thin films
, 2020 In this paper, we aim at a reduced 2 d -model describing the observable states of the magnetization in curved thin films. Under some technical assumptions on the geometry of the thin-film, it is well-known that the demagnetizing field behaves like the ...

Spin current pumped by confined breathing skyrmion
New Journal of Physics, 2020 Spin pumping is a widely recognized method to generate the spin current in the spintronics, which can be found in varieties of magnetic materials and is acknowledged as a fundamentally dynamic process equivalent to the spin-transfer torque. In this work,
