| Abstract: | A magnon soft mode in Mn2-xCrxSb in the vicinity of the Brillouin zone boundary in c1 direction, for the first order antiferro-ferrimagnetic phase transition, and the magnetization curve of the antiferromagnetic phase were measured. It was found that the soft mode energy squared is a linear function of temperature over a wide temperature range below and above the phase transition point. |
