Micromagnetic simulation of exchange coupled ferri-/ferromagnetic composite in bit patterned media
Harald Oezelt, Alexander Kovacs, Phillip Wohlhüter +6
Ferri-/ferromagnetic exchange coupled composites are promising candidates for bit patterned media because of the ability to control the magnetic properties of the ferrimagnet by it…
Numerical optimization of writer geometries for bit patterned magnetic recording
A. Kovacs, H. Oezelt, S. Bance +6
A fully-automated pole-tip shape optimization tool, involving write head geometry construction, meshing, micromagnetic simulation and evaluation, is presented. Optimizations have b…
An ESPResSo implementation of elastic objects immersed in a fluid
Ivan Cimrak, Markus Gusenbauer, Iveta Jancigova
We review the lattice-Boltzmann (LB) method coupled with the immersed boundary (IB) method for the description of combined flow of particulate suspensions with immersed elastic obj…
LaBonte's method revisited: An effective steepest descent method for micromagnetic energy minimization
Lukas Exl, Simon Bance, Franz Reichel +3
We present a steepest descent energy minimization scheme for micromagnetics. The method searches on a curve that lies on the sphere which keeps the magnitude of the magnetization v…
Non-uniform FFT for the finite element computation of the micromagnetic scalar potential
Lukas Exl, Thomas Schrefl
We present a quasi-linearly scaling, first order polynomial finite element method for the solution of the magnetostatic open boundary problem by splitting the magnetic scalar poten…
magnum.fe: A micromagnetic finite-element simulation code based on FEniCS
Claas Abert, Lukas Exl, Florian Bruckner +2
We have developed a finite-element micromagnetic simulation code based on the FEniCS package called magnum.fe. Here we describe the numerical methods that are applied as well as th…
FFT-based Kronecker product approximation to micromagnetic long-range interactions
Lukas Exl, Claas Abert, Norbert J. Mauser +3
We derive a Kronecker product approximation for the micromagnetic long range interactions in a collocation framework by means of separable sinc quadrature. Evaluation of this opera…
Numerical Methods for the Stray-Field Calculation: A Comparison of recently developed Algorithms
Claas Abert, Lukas Exl, Gunnar Selke +2
Different numerical approaches for the stray-field calculation in the context of micromagnetic simulations are investigated. We compare finite difference based fast Fourier transfo…
Fast stray field computation on tensor grids
Lukas Exl, Winfried Auzinger, Simon Bance +3
A direct integration algorithm is described to compute the magnetostatic field and energy for given magnetization distributions on not necessarily uniform tensor grids. We use an a…
