Abstract

In ordinary ferromagnets, individual magnetic moments tend to align with their neighbors, as long as temperatures are below the critical Curie temperature of the material. Cubic chiral magnets are a class of dominantly ferromagnetic, or rarer ferrimagnetic, materials with a literal twist. Due to broken inversion symmetry, weak spin-orbit coupling can induce a competing Dzyaloshinskii-Moriya interaction, which twists the magnetic texture into helical structures. One of these textures is of special interest to us. In it, the magnetization twists into whirl-like topological structures, called skyrmions. Here, we will explore various aspects of the equilibrium and non-equilibrium properties of chiral magnets.
