Abstract
Films of Fe0.79Ge0.21 were synthesized by ion beam sputtering, and wer e annealed at temperatures from 150 to 500 degrees C. The as-prepared materials comprised chemically disordered bcc crystallites, but short- range and long-range D0(3) chemical order developed upon annealing. Th e Fe-57 hyperfine magnetic field distribution can be understood approx imately with a model of magnetic response, so the hyperfine magnetic f ield distribution can be used to follow the changes in chemical short- range ordering. Large local isomer shifts were observed at Fe-57 atoms near Ge atoms.
