Mössbauer studies of moment distribution in amorphous ferromagnetic alloys

A spin spatial distribution in terms of an expansion in spherical harmonics containing deviation parameters from the symmetry axis P (0, ?) is used to describe the moment distribution of amorphous ribbon alloys. According to the theoretical analysis and Mössbauer measurement, P (0, ?) values and squareness S_xy (0, ?) and S_z can be obtained. The P (0, ?) distribution of FeNiSiBC and hydrided FeCrSiB amorphous alloys are studied.
