Аннотация
The low-frequency phase modulation of a radio-frequency field is used to excite a low-frequency collective mode in the Bose−Einstein condensate (BEC) of quasinuclear magnons in an antiferromagnetic material with the Suhl−Nakamura interaction. This oscillation mode is similar to the Goldstone torsional mode observed in antiferromagnetic superfluid 3He–B. The results clearly demonstrate the existence of the BEC in the systems under study.
