Sublattice contributions to the magnetism of UFe5Al7 and UFe6Al6.

Original language description

Magnetization study of intermetallic compounds UFe5Al7 and UFe6Al6 with the tetragonal crystal structure is performed on single crystals. The compounds are ferromagnets with Curie temperatures of 275 K and 315 K, respectively, and possess large magnetocrystalline anisotropy of the easy-plane type with the anisotropy field exceeding 20 T. In both UFe5Al7 and UFe6Al6, a noticeable anisotropy within the basal plane is observed with the [110] axis as the easy-magnetization direction, the [100] curve saturates in fields above 1 T. The in-plane anisotropy is the evidence for the U magnetism because it was not observed in Lu analogue. The large anisotropy persists in the paramagnetic state as well, again due to the U sublattice because it is absent in LuFe6Al6. Magnetic moments of the U and Fe atoms are estimated as 1.8 ?B and 1.3 ?B, respectively.
