Network of localized magnetic textures revealed using a saddle-point search framework
Hendrik Schrautzer, Tim Drevelow, Hannes Jónsson +1
A computational framework is presented for the sampling of the energy surface of magnetic systems via the systematic identification of first-order saddle points that determine conn…
Impact of higher-order exchange on the lifetime of skyrmions and antiskyrmions
Hendrik Schrautzer, Moritz A. Goerzen, Bjarne Beyer +3
Reliable control of skyrmion lifetime is essential for realizing spintronic devices, yet the role of higher-order exchange - which can lead to skyrmion stabilization - remains larg…
Time Reversible Integration of the Landau-Lifshitz-Gilbert Equation
Moritz Sallermann, Thorsteinn Freygardsson, Sergei Egorov +3
A method for time-reversible numerical integration of the deterministic Landau-Lifshitz Gilbert equation by means of a second order Suzuki-Trotter decomposition is presented and te…
Eigenmode following for direct entropy calculation and characterization of magnetic systems
Stephan von Malottki, Moritz A. Goerzen, Hendrik Schrautzer +2
We present an eigenmode following method (EMF) that has been developed for the numerical scanning of the potential energy surface and the direct calculation of entropy and pre-expo…
Co-existing magnetization reversal mechanisms in shakti spin ice systems
Vladyslav M. Kuchkin, Unnar B. Arnalds, Hannes Jónsson +1
The switching mechanisms in artificial spin ice systems are investigated with focus on shakti and modified shakti lattices. Minimum energy paths are calculated using the geodesic n…
Identification of mechanisms of magnetic transitions using an efficient method for converging on first order saddle points
Hendrik Schrautzer, Moritz Sallermann, Pavel F. Bessarab +1
A method for locating first order saddle points on the energy surface of a magnetic system is described and several applications presented where the mechanism of various magnetic t…
