Influence of Co on the magnetism of HoFe5Al7

Original language description

Effects of the Co substitution for Fe on the ferrimagnet HoFe5Al7 are studied on single crystals. For HoFe5-xCoxAl7, we found the homogeneity range up to x=2.5. The Co substitution results in a small shrinkage of the tetragonal lattice within the basal plane, whereas the c parameter does not change. The detrimental effect of Co on the Curie temperature is very unusual. It falls linearly from 216 K for x=0 to 67 K for x = 2.5, which is unexpected because the Co substitution for Fe in 3d-4f intermetallic compounds usually increases the ordering temperatures. The compensation temperature changes very little between 65 K and 72 K. The compounds exhibit a high magnetic anisotropy of the easy-plane type with the easy axis [110]. Along the easy axis, two first-order field-induced magnetic transitions (at 17 T and 37 T) are observed for x=0 and one transition at 27 T for x=1. The magnetization curve has an S-shape for x=2.n
