Abstract

Relaxation in magnetisation of metastable states is reported. The states are prepared by supercooling a Ce(Ru, 5% Nd)2 alloy sample to different extents through similar paths in the H-T space, and then by applying a field jerk of 20 Oe of either sign. Based on standard theory, a possible explanation is put forward.
