Magnon Bose-Einstein condensation at inhomogeneous conditions

Abstract

The Spin Supercurrent and Bose-Einstein condensation of magnons, similar to an atomic BEC, was discovered in superfluid 3He-B, which is characterized by absolute purity. Later this phenomena were observed in a few magnetically ordered materials with different types of impurities. In this article we will review the properties of magnon BEC in a presence of impurities and defects. © Published under licence by IOP Publishing Ltd
