Clear experimental evidence of re-entrant spin glass state has been revealedin Er doped CeFe2 compounds. The zero field cooled - field cooled bifurcationin dc magnetization, frequency dependence of freezing temperature, relaxationin zero field cooled magnetization and presence of large remanence confirm thespin glass state in these compounds. Frequency dependence is found to followthe critical slowing down mechanism. The random substitution of Er and thechange in the valence state of Ce along with an enhancement of theferromagnetic component in the Fe sublattice seem to be responsible for thespin glass state. Using detailed experimental protocols, we also prove that thelow temperature state in these compounds is not a magnetic glass. The absenceof exchange bias gives an indication that there is no coexistence offerromagnetism and spin glass state in these compounds. The RSG state is foundto be associated with the randomly magnetized clusters instead of atomic levelrandomness.
