摘要：

The magnetic moment of CrxMn1-xAs mixed crystals has been measured for temperatures between 3 and 400 K and for ten different compositions between x = 0 and x = 1. Measurements of the electrical resistivity have been added in order to achieve an unambiguous identification of the various magnetic ordering temperatures. The combination of all the data enabled us to construct the complete magnetic phase diagram. It is found that the transition from antiferromagnetic CrAs to ferromagnetic MnAs is very complex. We propose to explain the transition as an interplay of two competing double exchange-superexchange coupling mechanisms. © 1979.
