Skyrmion Crystal in a Microwave Field
arXiv:2502.16340 · doi:10.1103/plt1-7f6d
Abstract
Temperature and field dependences of the frequencies of uniform modes of the skyrmion lattice in a 2D ferromagnetic film with Dzyaloshinskii-Moriya interaction, as well as their damping, are computed within the model of classical spins. We show that the magnetization of the film exhibits Rabi-like oscillations when subjected to the microwave field at resonance with the low-frequency mode. Melting of the skyrmion lattice by resonant microwaves is investigated in terms of the time dependence of the orientational and translational order parameters. A distinct single-stage melting transition has been observed.
