Micromagnetic simulations of absoption spectra [PDF]
Journal of Magnetism and Magnetic Materials, 2006 Further development of a previously introduced method for numerically simulating magnetic spin waves is presented. Together with significant improvements in speed, the method now allows one to calculate the energy absorbed by the various modes excited by a position- and time-dependent H1 field in a ferromagnetic body of arbitrary shape in the presence ...

Micromagnetic simulations of magnetoelectric materials [PDF]
Journal of Applied Physics, 2011 Some magnetic materials show a magnetoelectric coupling between inhomogeneous magnetization patterns and electric polarization that is sufficiently strong to allow external control of magnetization structure by electric fields. Numerical simulations of “magnetoelectric” materials of this type require an extension of the standard micromagnetic model ...

The stability of a skyrmion in a nanotube
New Journal of Physics, 2019 We study the stability of a skyrmion in a nanotube by using micromagnetic simulations. We find that skyrmions can exist stably in a nanotube within a moderate magnetic field range when the magnetic field is perpendicular to the center axis of the ...

Optimizing machine learning models for granular NdFeB magnets by very fast simulated annealing
Scientific Reports, 2021 The macroscopic properties of permanent magnets and the resultant performance required for real implementations are determined by the magnets’ microscopic features. However, earlier micromagnetic simulations and experimental studies required relatively a

Micromagnetic simulation of Fe asymmetric nanorings
Journal of Magnetism and Magnetic Materials, 2012 During the last decade several methods to control the vortex chirality in nanodots have been proposed. One of them, the introduction of asymmetry in the geometry of the dots, originates interesting effects on the magnetic behavior of the particle.

Current-driven skyrmion motion along disordered magnetic tracks
AIP Advances, 2017 The motion of skyrmions along ferromagnetic strips driven by current pulses is theoretically analyzed by means of micromagnetic simulations. Analytical expressions describing the skyrmion dynamics during and after the current pulse are obtained from an ...

Micromagnetic simulations of first-order reversal curves in nanowire arrays using MuMax3
AIP Advances, 2019 We perform simulations of magnetic reversal in a 3 × 3 array of nanowires using MuMax3 micromagnetic simulation program. We record a series of first-order reversal curves (FORCs) that form distinct branches of ascending minor curves depending on the ...
