Proposal for a micromagnetic standard problem: domain wall pinning at phase boundaries

Paul Heistracher, Claas Abert, Florian Bruckner +2

We propose a novel micromagnetic standard problem calculating the coercive field for unpinning a domain wall at the interface of a multiphase magnet. This problem is sensitive to d…

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…

A repulsive skyrmion chain as guiding track for a race track memory

Dieter Suess, Christoph Vogler, Florian Bruckner +1

A skyrmion racetrack design is proposed that allows for thermally stable skyrmions to code information and dynamical pinning sites that move with the applied current. This concept…

Spin Torque Efficiency and Analytic Error Rate Estimates of Skyrmion Racetrack Memory

Dieter Suess, Christoph Vogler, Florian Bruckner +2

In this paper the thermal stability of skyrmion bubbles and the critical currents to move them over pinning sites is investigated. For the used pinning geometries and the used para…
