Local atomic structure and hyperfine interactions in electrodeposited Fe100−xPx (1.8 <x < 45) alloys

Abstract

Electrodeposited Fe–P alloys with P concentration up to 45 at% are studied by Mössbauer spectroscopy. The concentration dependences of average hyperfine magnetic fields H(x) and isomer shifts H(x) are measured. The values of local hyperfine magnetic fields HK depending on the P-atom numbers in the nearest Fe-atom environment are determined. Conclusions about changes in the local atomic structure of Fe–P alloys with P concentration increasing from 7 up to 25 at% are drawn. From the H(x) dependence the possibility of describing integral macrophysical properties of Fe–P alloys using local atomic environment characteristics, is illustrated. [Russian Text Ignored].
