High magnetic field properties of GdIn3

Both, the magnetisation and the magnetoresistivity of a GdIn3 single crysta l have been investigated at 4.2 K in magnetic fields up to 40 T. The magnet isation shows an almost linear dependence on the applied field and reaches a value of only 3.4 mu(B)/Gd-atom at the highest applied field strength. Th e magnetoresistance shows a saturation-type of dependence on the field. Bot h quantities investigated display a distinct anomaly at about 30 T in their field dependencies. A possible origin of this field-induced anomaly will b e discussed. (C) 2000 Elsevier Science B.V. All rights reserved.
