FexTi100-x alloys over a wide composition range has been made by high-rate sputtering and studied by 57Fe Mössbauer spectroscopy. Samples with 30≤x≤80 are amorphous whereas samples with x≥85 are metastable crystalline bcc alloys. Large differences in magnetic properties (e.g., TC) and hyperfine interactions (H eff, isomer shift) are found between the amorphous and bcc alloys. Comparison of FeTi and Fe2Ti in amorphous and crystalline states show that the short-range order in the amorphous state has no resemblence to that of the crystalline compounds.
