Abstract

Fe_xTi_100-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., T_C) 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.
