The design, verification and performance of MUMAX3, an open-source GPU-accelerated micromagnetic simulation program that solves the time- and space dependent magnetization evolution in nano- to micro scale magnets using a finite-difference discretization is reported on.Abstract:
We report on the design, verification and performance of MUMAX3, an open-source GPU-accelerated micromagnetic simulation program. This software solves the time- and space dependent magnetization evolution in nano- to micro scale magnets using a finite-difference discretization. Its high performance and low memory requirements allow for large-scale simulations to be performed in limited time and on inexpensive hardware. We verified each part of the software by comparing results to analytical values where available and to micromagnetic standard problems. MUMAX3 also offers specific extensions like MFM image generation, moving simulation window, edge charge removal and material grains.read more

TL;DR: This work designed cobalt-based multilayered thin thin metals in which the cobalt layer is sandwiched between two heavy metals and so provides additive interfacial Dzyaloshinskii-Moriya interactions (DMIs), which reach a value close to 2 mJ m(-2) in the case of the Ir|Co|Pt asymmetric multilayers.

TL;DR: This study demonstrates a method leading to the formation of magnetic skyrmions in a micrometer-sized track using homogeneous current injection and addresses the particularly important role of the magnetic inhomogeneities on the current-induced motion of sub-100 nm skyrMions for which the material grains size is comparable to theskyrmion diameter.

TL;DR: It is demonstrated that room-temperature antiferromagnetic skyrmions can be stabilized in synthetic antiferromaagnets (SAFs), in which perpendicular magnetic anisotropy, antiferromeagnetic coupling and chiral order can be adjusted concurrently.
