Skyrmion glass in a 2D Heisenberg ferromagnet with quenched disorder

Skyrmion glass in a 2D Heisenberg ferromagnet with quenched disorder

A 2D Heisenberg ferromagnet with exchange J and random magnetic anisotropy of strength ${D}_{R}\ll J$ has been studied. Analytical theory for the dependence of the average size of a pinned skyrmion on the magnetic field H , and for stability of such skyrmions on a lattice, has been developed. It has...
