Creating Skyrmions in Thin CoPt Films with an Atomic Force Microscope Probe

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

Methods of magnetic force microscopy are developed that make it possible to visualize the evolution of the domain structure that occurs when scanning a sample with a magnetic probe. The new technique is used to study the formation in CoPt thin films the skyrmions, a characteristic feature of which is Dzyaloshinskii–Moriya interaction. Changes in the position, shape, and size of the skyrmions when exposed to the probe’s magnetic field are described experimentally.
