Query: First order phase transition from ferromagnetism to antiferromagnetism
  in Ce(Fe$_{0.96}$Al$_{0.04}$)$_2$   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.
