Post-annealing results represented by lines of different colors. (a) DTA-TG curve for sample S1 which was performed in Ar atmosphere from 60°C to 1,200°C. (b) The representative XRD patterns for sample S1 annealed at 200°C, 400°C, and 800°C. (c) M-H curves of the post-annealing samples. (d) Variation of Ms for sample S1 after post-annealing processes.
