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…
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…
Metaheuristic conditional neural network for harvesting skyrmionic metastable states
Qichen Xu, I. P. Miranda, Manuel Pereiro +8
We present a metaheuristic conditional neural-network-based method aimed at identifying physically interesting metastable states in a potential energy surface of high rugosity. To…
