Long-lived free induction decay signal in CsMnF3 single crystal
Abstract
Elementary excitations in antiferromagnets are magnons, and these quasiparticles with integer spin are governed by Bose statistics. In certain conditions their density can be controlled by applied radiofrequency pulse leading to the formation of Bose-Einstein condensation (BEC). We report the investigations of free induction decay signal duration in CsMnF3 under different conditions and discuss it in the framework of the magnon BEC. The observed results in CsMnF3 and previous investigations in superfluid 3He-A are compared.
Supporting agencies: The work is performed according to the Russian Government Program of Competitive Growth of Kazan Federal University and partly supported by the Russian Foundation for Basic Research (project no. 14-02-31290 mol a).
