Abstract
Recently, the stabilization of antiskyrmions in the presence of anisotropic Dzyaloshinskii–Moriya interaction and its dynamics have been investigated. Here, we report the antiskyrmion motion with the combined action of the in-plane magnetic field and perpendicular microwave electric fields. The in-plane magnetic field breaks the rotation symmetry of the antiskyrmion, and the microwave electric field induces the parametric pumping of magnetic anisotropy, leading to antiskyrmion breathing mode. Antiskyrmion moving velocity depends on the frequency, amplitude of anisotropy pumping, and damping constant as well as strength of in-plane field, which reaches the maximum value when the frequency of microwave electric field is in consist with the resonance frequency of antiskyrmion. Moreover, we show that the antiskyrmion motion depends on the direction of magnetic field, where the antiskyrmion Hall angle can be suppressed or enhanced. At a critical direction of magnetic field, the Hall angle is zero. Our results introduce a promising manipulation method for antiskyrmion in both metallic and insulating magnetic materials, and also provide a guidance for the design and application of antiskyrmion-based spintronic devices with lower energy consumption.
