Figure 1. (A) Magnetic structures of Mn3Pt alloys with triangular AFM and colinear AFM phases as reported by Tao et al.[27]. (B-D) heat flow vs. temperature curves, the contour plots of the variable temperature XRD patterns and lattice constant vs. temperature curves for sample x = 0.1, respectively. The inset in (C) is an enlarged image of the high Q region.
