Epitaxial Thin Films of the Cubic B20 Chiral Magnets

Bulk B20 magnets exhibit an exotic skyrmion phase in a narrow phase region at a temperature close to Curie temperature within a magnetic field. The investigation and exploitation of these exotic phases, and especially potential devices, require thin films. In this chapter, we discuss the epitaxial growth, the unusual magnetic and transport properties, with the strong thickness dependence of the B20 films. We have also realized an extended skyrmion phase in thin films.
