Magnetic properties of the pseudobinary bct FeRh1−xPtx alloys were investigated from the viewpoints of a lattice distortion and a magneto-volume effect. The axial ratio, ca, varies from 1.185 to 1.359 with increasing x from 0 to 1.0. In x < 0.72, the Curie temperature was found to be lower than the antiferromagnetic-ferromagnetic transition temperature and, consequently, the first order phase transition from the antiferromagnetic state to the paramagnetic state was observed.
