Skyrmions in applied electric fields

DOI

One of the most studied skyrmion-hosting materials is the magnetoelectric insulator Cu2OSeO3 which raises the exciting prospect of manipulating the skyrmion-phase through the application of electric-fields. Using longitudinal field (LF) muSR we see an enhanced relaxation in the SkL phase in various systems, including Cu2OSeO3. We believe the observed peak in relaxation rate includes contributions from critical slowing of magnetic fluctuations down near the phase transition, as well as enhanced dynamics within the SkL phase, reflecting the emergent excitations of the skyrmions. Here we propose extending our study of the SkL with LF muSR measurements on Cu2OSeO3 under an applied electric field, allowing us to explore the electric-field induced change in dynamics, and to further explain the mechanism of skyrmion creation and annihilation.
