説明

The effect of the pressure on the Curie temperature of CrTe and MnSb compounds of the nickel arsenide type structure were studied up to 4, 000 kg/cm^2. The rate of change of the Curie temperature was -5.5×10^<-3>℃ kg^<-1>cm^2 for CrTe and (-3.2±0.5)×10^<-3>℃ kg^<-1>cm^2 for MnSb. From the result of the present experiment, the critical pressure and temperature to realize a first kind transition from a ferromagnetic to a paramagnetic state in CrTe are evaluated to be 41, 000 kg/cm^2 and 107°K, respectively.
