Electric-Field Control of Magnetization Dynamics in Antiferromagnets

The Dzyaloshinskii-Moriya interaction (DMI) under an external electric field-effect generates additional phase called the Aharonov-Casher phase that is an example of a global topological effect in the magnetization dynamics. The electric field effects on spin-waves (SWs) dynamic in a two-sublattice antiferromagnet (AFM) structure have been studied within a phenomenological approach. Due to the presence of DMI SW spectrum shows the splitting between the right-handed and left-handed SWs. The obtained results are important for controlling SWs and constructing spintronic devices.
