High-field magnetization studies of some U2T2X compounds

1995 
Abstract High-field magnetization measurements at 4.2 K on several U 2 T 2 X (T = Ni, Rh, Pd, Pt; X = In, Sn) compounds have been performed on free and fixed powders up to 57 T. An antiferromagnetic ground state of U 2 Ni 2 Sn is corroborated by metamagnetic transitions at 30, 39 and 51 T. U 2 Rh 2 Sn shows one metamagnetic transition at 21 T and U 2 Pd 2 Sn two metamagnetic transitions at 39 and 45 T. U 2 Pt 2 In shows no metamagnetism up to 57 T which is in agreement with the non-magnetic ground state of this compound. The short-pulsed measurements up to 57 T are compared with previous results obtained in quasi-static fields up to 35 T.
