Abstract

Band structure calculations were performed on disordered FexPt100-x alloys as well as on FePt and Fe3Pt ordered phases. The equilibrium values of the lattice parameters, magnetic moments, Curie temperatures, pressure effects, as well as spontaneous volume magnetostrictions were obtained and compared with experimental data. It was shown that the computed values as well as the experimental data can be described starting from Néel−Slater curve. The spin glass behaviour observed in fcc FexPt1-x alloys, when decreasing lattice parameters, simulating the pressure effect, is also discussed..

Keywords
