Description 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: tau = tau(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. Copyright (C) EPLA, 2010
