Quadrupole splitting distributions of amorphous transition metal-metalloid alloys

Abstract
The technique of radio-frequency collapse is used to determine the quadrupole splitting distributions of ferromagnetic amorphous alloys, FexNi75-xSi10B15 and FexSi90-xB10. In both cases the concentration dependence of the average quadrupole splitting QS, determined by Mossbauer spectroscopy, suggests a change in short-range order as predicted by structural models.
