Abstract

Taking the pseudobinary C15 Laves phase compound Ce(Fe $_{0.96}$ Al $_{0.04}$ ) $_{2}$ as a paradigm for studying a ferromagnetic to antiferromagnetic phase transition, we present interesting thermomagnetic history effects in magnetotransport as well as magnetisation measurements across this phase transition. A comparison is made with history effects observed across the ferromagnetic to antiferromagnetic transition in R $_{0.5}$ Sr $_{0.5}$ MnO $_{3}$ crystals.
