(a), (b), and (c) Temperature dependent FCC and FCW magnetization curves under different magnetic field of S1250, S750, and S950 samples, respectively. (d) Magnetic field and particle size dependent T C of all the samples measured upon cooling.
(a) Variation of ΔT in magnetization with particle sizes at H = 10 kOe field. (b), (c), and (d) Arrott plots of S950, S1250, and S750 sample, respectively.
(a) and (b) χ −1(T) under H = 100 Oe of all the samples. The dashed lines are the best fit curves using CW law. Inset of (a) shows the variation of θ with particle size. Inset of (b) shows the variation of P eff and λ (molecular field constant) with particle sizes.
