  • The magnetic moment M and the specific resistivity ϱ of CrxMn1−xAs polycrystals are measured for temperatures between 5 and 300 K and for eight different compositions. Structures in the ϱ(T) and M(T) curves define characteristic temperatures which are used to construct a magnetic phase diagram. The large number of magnetic phases between ferromagnetic MnAs and antiferromagnetic CrAs are explained on the basis of two competing superexchange–double exchange magnetic couplings.
