Figure 3.
Magnetisation measurements, (a) Temperature dependence of the magnetisation with an external field of 50 Oe under FC and ZFC conditions. The red solid line with open circles is under the FC condition and the blue dashed line with filled circles is under the ZFC condition. (b) M-H curve measured at 2 K. The circles are the data points and the lines are visual guides in both (a) and (b).
