EXAFS study of Mn 1.28 Fe 0.67 P 0.46 Si 0.54 compound with first-order phase transition
Journal of Electron Spectroscopy and Related Phenomena(2014)
摘要
•We have investigated the Fe and Mn K edge XAFS spectra of the Mn1.28Fe0.67P0.46Si0.54 compound at 25K and 295K.•The site occupation of the Fe and Mn atoms and local structure of Mn1.28Fe0.67P0.46Si0.54 are determined.•The atomic distances between Fe–Fe in c-plane for the ferromagnetic state are larger than those in the paramagnetic state.
