Temperature-dependent synchrotron X-ray powder diffraction patterns. Evolution of synchrotron X-ray powder diffraction patterns of Ni1.9Pt0.1MnGa as a function of temperature during a cooling cycle for 3 selected 2θ ranges. The (220) austenite peak region is shown in a, the satellite region in d, and the (224) austenite peak region in e. b, c represent the (220) austenite peak region with an expanded scale for selected temperatures. A, PM, and M represent the Bragg peaks of the cubic austenite, premartensite, and martensite phases, respectively. The inset in b shows the Bragg reflections at the extended scale in the 2θ range between 6.20 and 6.38 where the satellite reflection of 3 M modulated premartensite phase is expected
