Abstract:

Crystal structure, magnetization and specific-heat studies were performed on (U1-xLux)NiGa solid solutions in order to investigate effects of the U sublattice dilution by Lu on antiferromagnetism in UNiGa. In contrast to a number of transitions observed in UNiGa, the Lu substituted materials exhibit only one magnetic phase transition at which they order antiferromagnetically. Both the temperature of magnetic ordering and the estimated Il magnetic moment decrease almost linearly with increasing x and vanish around x=0.3 which is accompanied by vanishing magnetic entropy. Simultaneously the critical field of metamagnetic transition increases but the transition obviously disappears for x>0.2. The rapid loss of magnetism with dilution of the U sublattice by nonmagnetic Lu is attributed to the band character of magnetic U 5f electrons. (C) 2001 Elsevier Science B.V. All rights reserved.
