Abstract:
Results of experiments in which the Bose-Einstein condensate of magnons is created in the CsMnF 3 easy-plane antiferromagnet in a system with coupled nuclear-electron precession with dynamical frequency shift are presented. This condensate is similar to the Bose-Einstein condensate of magnons in superfluid 3He-A in aerogel. © 2011 Pleiades Publishing, Ltd.
