Abstract

The U contribution to the total magnetic moment of U2Fe13.6Si3.4 is almost negligible. Nevertheless, U strongly influences the magnetic properties. A considerable U spin moment is evident from the enhanced Curie temperature of U2Fe13.6Si3.4 (530K) compared to that of Lu2Fe13.6Si3.4 (470K). Evidence for a considerable U orbital moment is the strongly enhanced magnetic anisotropy of U2Fe13.6Si3.4 compared to that of Lu2Fe13.6Si3.4. Both the Fe and the U sublattices provide the magnetic anisotropy of the easy-plane type. The U sublattice gives rise to a large negative K2, which is manifested in the strong non-linearity of the magnetization curve and in the field-induced phase transition. The anisotropy within the basal plane with the easy magnetization axis 〈 120 〉, absent in the Lu compounds, is observed in U2Fe13.6Si3.4.
