Abstract

This paper presents a study of the spin reorientation of Nd 0.5Pr 0.5Co 4Ga and Nd 0.5Er 0.5Co 4Ga by magnetic measurements. Their spin reorientation temperatures are 227 and 165 K respectively. The magnetic dilution of Co sublattice by Ga reduces considerably the Curie point of the corresponding RCo 5 compounds but it does not seem to affect the spin reorientation temperature of the former compound with respect to NdCo 5 while Er reduces the spin reorientation of NdCo 5 considerably. The obtained results are compared with other results of relative compounds given in the literature.
