(color online) (a) M–T curves for sample with x = 0.12 under magnetic fields of 0.1 (blue) and 5 T (orange). Dark green and pink curves are for fitted curves. (b) Red curve denotes ΔV vs temperature with magnetic field variation of 0–5 T. Blue dotted curve refers to temperature dependence of with the magnetic field variation of 0–5 T.
