Abstract :
Structural and magnetic properties of the Pr2Fe6.8 Co10.2-xMx intermetallic compounds with M=Si, Ga and V, and x=0, 0.5, 1.0, 1.5 and 2.0 have been investigated. Substitution of M for Co leads to a decrease of the saturation magnetization, Curie temperature, and anisotropy field. It is noteworthy that the V substitution has different influence on the magnetic properties of the Pr2Fe6.8Co10.2 compounds from the Si and Ca substitutions, The spin-reorientation temperature decreases with increasing M for M=Si and Ga. This phenomena disappeared when M=V, and the saturation magnetization of the V substituted compounds decreased much faster than those of the Si and Ga substituted compounds
