Micromagnetic simulations of absoption spectra [PDF]
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 ...

Tuning magnetic chirality by dipolar interactions [PDF]
Chiral magnetism has gained enormous interest in recent years because of the anticipated wealth of applications in nanoelectronics. The demonstrated stabilization of chiral magnetic domain walls and skyrmions has been attributed to the actively ...

Micromagnetic simulations of magnetoelectric materials [PDF]
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
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 ...

Micromagnetic simulation of antiferromagnetic/ferromagnetic structures [PDF]
A novel approach for solving the Landau-Lifshitz-Gilbert equation for antiferromagnets with the finite-element method is presented. The antiferromagnet is treated in a continuum theory which allows us to explore the domain structure on a mesoscopic length scale.

Time-resolved investigation of magnetization dynamics of arrays of non-ellipsoidal nanomagnets with a non-uniform ground state [PDF]
We have performed time-resolved scanning Kerr microscopy (TRSKM) measurements upon arrays of square ferromagnetic nano-elements of different size and for a range of bias fields. The experimental results were compared to micromagnetic simulations of model

Manipulating 1-dimensional skyrmion motion by the external magnetic field gradient
We have investigated an approximated analytic form of the one-dimensional motion of skyrmions accelerated by a gradient of the external magnetic field. We find excellent agreement between the analytical calculations and micromagnetic simulations when the

Micromagnetic simulation of Fe asymmetric nanorings
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.
