Figure 17: Mössbauer spectra of ordered Fe3Pt alloy. (Cooling rate of the high temperature heating is about 1°C × min−1). (a) Foil with completely ordered fcc structure obtained after annealing at 640°C for 48 h followed by cooling to room temperature. The spectrum consists of a sextet with H = 22.6 T; (b) spectrum of the foil after heating at 1100°C for 4 h followed by cooling to room temperature. The ordered fcc phase with a noticeable fraction of the bcc phase. Both structures are deformed. The spectrum consists of a sextet with H = 26.3 T.
