Dependence of energy barrier reduction on collective excitations in square artificial spin ice: A comprehensive comparison of simulation techniques
Sabri Koraltan, Matteo Pancaldi, Naëmi Leo +9
We perform micromagnetic simulations to study the switching barriers in square artificial spin ice systems consisting of elongated single domain magnetic islands arranged on a squa…
Hybrid FFT algorithm for fast demagnetization field calculations on non-equidistant magnetic layers
Paul Heistracher, Florian Bruckner, Claas Abert +2
In micromagnetic simulations, the demagnetization field is by far the computationally most expensive field component and often a limiting factor in large multilayer systems. We pre…
Large Scale Finite-Element Simulation of Micromagnetic Thermal Noise
Florian Bruckner, Massimiliano d'Aquino, Claudio Serpico +3
An efficient method for the calculation of ferromagnetic resonant modes of magnetic structures is presented. Finite-element discretization allows flexible geometries and location d…
GPU Accelerated Atomistic Energy Barrier Calculations of Skyrmion Annihilations
Paul Heistracher, Claas Abert, Florian Bruckner +2
We present GPU accelerated simulations to calculate the annihilation energy of magnetic skyrmions in an atomistic spin model considering dipole-dipole, exchange, uniaxial-anisotrop…
A fast finite-difference algorithm for topology optimization of permanent magnets
Claas Abert, Christian Huber, Florian Bruckner +3
We present a finite-difference method for the topology optimization of permanent magnets that is based on the FFT accelerated computation of the stray-field. The presented method e…
AC noise reduction based on exchange coupled grains for heat-assisted-magnetic recording: The effect of an FeRh interlayer
Christoph Vogler, Claas Abert, Florian Bruckner +1
High storage density and high data rate are two of the most desired properties of modern hard disk drives. Heat-assisted magnetic recording (HAMR) is believed to achieve both. Reco…
