Abstract:
Magnetic susceptibilities have been measured for the mixed compounds Mn1−xCrxAs (0≤x≤1) and the compound MnP in the temperature region up to 1400 K. The X1g vs. T curves of Mn1−xCrxAs follow the Curie-Weiss law only in the temperature region where the crystal structure is of the B81 type. Some important problems are pointed out from the data.
