Experimental evidence of re-entrant spin glass (RSG) state has been revealed in Er-doped CeFe 2 compounds. The zero-field–cooled - field-cooled bifurcation in dc magnetization, frequency dependence of freezing temperature, relaxation in zero-field–cooled magnetization and presence of large remanence have been discussed in detail. Frequency dependence is found to follow the critical slowing-down mechanism of the type: τ = τ 0 ( T f / T SG −1) − zv . The RSG state is found to be associated with the randomly magnetized clusters instead of atomic level randomness.
