Abstract

This work reveals that an ultra-fast emergent electric field can be generated during the ultra-fast propagation of Bloch points in skyrmionic textures. The authors show the feasibility of tuning the generation process, as well as the amplitude and frequency of this electric signal by demonstrating a manipulation of Bloch-point dynamics.
