Figure 2. (A-D) Magnetization curves for samples x = 0.18, 0.1, 0.08, and 0.04, respectively. (E) Curves of phase transition temperature vs. manganese content x (blue squares and red dots indicate measurement by M-T and heat flow, respectively) and lattice constant vs. manganese content x for the samples. (Taking x = 0.08 as an example, the fitting parameters obtained using the lebail method to fit the XRD curve are: GOF = 1.47, Rp = 4.18, Rwp = 5.99). (F) The magnetization loop of x = 0.18. The inset shows the enlarged plot at low fields.
