Abstract

The magnetization study was performed on single crystals of uranium intermetallic compounds R₂T_13.6Si_3.4 (R=U, Lu; T=Fe, Co). A very different behavior of the U sublattice was observed for T=Fe and Co. In U₂Fe_13.6Si_3.4, the U sublattice is magnetic and contributes a lot to the exchange and anisotropy energies whereas in U₂Co_13.6Si_3.4 it is presumably non-magnetic. Influence of U in the latter case consists in reduction of the Co magnetic moments and exchange interaction between them, which causes a much lower molecular magnetic moment and Curie temperature in U₂Co _13.6Si_3.4 compared to Lu₂Co _13.6Si_3.4.
