Abstract
Disordered and DO3 type-ordered Fe75(Si1−x Gex)25 alloys are fabricated and investigated using x-ray diffraction, Mössbauer spectroscopy, and magnetic measurements. The variations in the magnetic and Mössbauer characteristics are interpreted using ab initio calculations of the electronic structure, magnetic moments, hyperfine magnetic fields, and isomer shifts. The main differences in the properties are related to the increase in the crystal lattice parameter when Si is replaced by Ge in ordered alloys and to a different behavior of the correlations in the Si and Ge positions in disordered alloys.
