Fig. 3
Rietveld fits for the synchrotron X-ray powder diffraction patterns of Ni1.9Pt0.1MnGa. Rietveld refinements at a 290 K (cubic austenite phase), b 240 K (premartensite phase), and c 110 K (martensite phase). The experimental data, fitted curve, and the residue are shown by circles (black), red continuous line, and green continuous line, respectively. The tick marks (blue) represent the Bragg peak positions. The insets show the fit for the main peak region on an expanded scale. Satellite reflections in the premartensite (PM) and martensite phases (M) are shown by (hklm)PM and (hklm)M, respectively
