First order transition from ferro- to antiferromagnetism in CeFe$_2$   based pseudobinary alloys
  We present results of ac susceptibility measurements highlighting the presence of thermal hysteresis and phase coexistence across the ferro-to antiferromagnetic transition in various CeFe$_2$ based pseudobinary systems. These results indicate that the ferro-to antiferromagnetic transition in these systems is first order in nature.
