Mössbauer study of the hyperfine fields at Fe sites in orthorhombic Fe3C1−xBx

Abstract

The orthorhombic Fe3C1−xBx system (0.6 < x < 0.8) was studied by Mossbauer Effect Spectroscopy at both 100K and room temperature. The data were analyzed by both assuming the existence of two and four hyperfine field distributions in the Mossbauer spectra. The extrapolation of our results to x=1 give values of 268 kOe and 238 kOe for the hyperfine field values at the crystallographic inequivalent Fe sites I and II in orthorhombic Fe3B. These results are in good agreement with the values previously reported by Choo and Kaplow/1/.
