Micromagnetic Modeling
Recent progress in material science has enabled the first experimental studies concerning the static magnetization characterization of samples with tubular geometry, such as rolled-up structures, nanowires and nanotubes. The bending of a flat thin-film to a curved surface introduces a break of the local inversion symmetry and can lead to surprising phenomena which do not unfold in flat geometries. As an example, domain walls in nanotubes show a chiral symmetry breaking regarding their propagation and moreover can propagate so fast that can trigger a Cherenkov-type spin-wave radiation. A further example is that this lack of inversion symmetry leads to an asymmetric dispersion relation for the spin waves regarding the sign of the propagation vector. This is a purely curvature induced effect with its origin in the classical dipole-dipole interaction.
To study the effect of curvature on the magnetization dynamics often requires the knowledge about the spin-wave eigenmode spectrum. This is usually obtained by micromagnetic simulations solving the equation of motion of magnetization. Despite their flexibility, the classical time-domain micromagnetic simulations can be time-consuming, rely on high-performance GPUs, and need extensive post-processing. Thus, they are not suited to study magnons in complex systems.
During the last year we developed a finite-element method to rapidly obtain the spin-wave spectra in waveguides with arbitrarily-shaped cross-sections without any post-processing. This reduced the computational time from several days to minutes. Part of this endeavor was developing a novel finite-element/boundary-element method to compute long-range fields generated by propagating magnons [L. Körber, et al., AIP Adv. 11, 095006 (2021)]. Due to its flexibility and usefulness for the study of spin waves, the method was made available to the scientific community in the open-source package TetraX.
TetraX is a package for finite-element-method (FEM) micromagnetic modeling with the aim to provide user friendly and versatile micromagnetic workflows. Apart from energy minimizers and an LLG solver, it aims to provide implementations of several FEM dynamic-matrix approaches to numerically calculate the normal modes and associated frequencies for magnetic specimen of different geometries such as confined samples, infinitely long waveguides, or infinitely extended multilayers. Apart from ferromagnets, the package also supports antiferromagnets as an experimental feature.
