Multiple first-order magnetic field-induced transitions in Pr2(CoxFe1−x)17 (x=0, 0.1, 0.2)

Abstract The compounds Pr2(CoxFe1−x)17 with x=0, 0.1, 0.2 exhibit a complex behaviour of the magnetic anisotropy: the occurrence of a normal approach to saturation, a type 1 FOMP, a double transition and a type 2 FOMP, are found in different temperature intervals. This phenomenology can be explained if a two sublattice system having competing anisotropies and the occurrence of canting angles between magnetic sublattices, during the magnetisation process, are considered.
