Magnonics and Supermagnonics

Abstract

© 2019 World Scientific Publishing Company. The magnetic community continues to discuss the possibility of observing the magnetic superfluidity, despite the fact that it has been discovered a long time ago. It was observed in antiferromagnetic states of superfluid 3He in 1984. In this paper, we reiterate the main principles of spin superfluidity and related Bose-Einstin magnon condensation. We discuss applications of this phenomenon in supermagnonic devises.
