Sommario:
- We theoretically propose a method to generate topological spin textures by irradiating a classical spin system with a linearly polarized AC electric field. To this end, we investigate non-equilibrium steady states in a classical Heisenberg model with frustrated exchange interactions on a two-dimensional triangular lattice by numerically solving the Landau-Lifshitz-Gilbert equation at zero temperature. Our results reveal that the linearly polarized AC electric-field irradiation induces a topological phase transition from a single-Q spiral state to a bimeron crystal with the skyrmion number of one in the low-frequency regime. Furthermore, we show that the obtained bimeron crystal remains relatively stable against both easy-axis and easy-plane single-ion anisotropies.
