FC/ZFC curves obtained at different temperatures and lack of hysteresis at room temperature. (a) FC at 100 Oe and ZFC show a bifurcation and the maximum magnetic moment in ZFC provides an estimate of the blocking temperature (T B), which is approximately 100 K; and (b) M-H curve at 300 K shows no hysteresis.
