Mössbauer study of ionic and metallic states of electrodeposited Fe−Ni−P amorphous alloys

Abstract

In this contribution we report cases in which we found ionic character of the amorphous state in electrodeposited Fe−Ni−P samples electroplated in a similar way but with different parameters to those exhibiting metallic amorphous character in their Mössbauer spectra. In particular, the room temperature transmission spectrum of an X-ray amorphous electrodeposited Fe₆₈Ni₂₃P₈ sample consists of two doublets with IS1=0.27 mm/s, QS1=0.51 mm/s, IS2=1.22 mm/s and QS2=2.54 mm/s parameters, where the latter is characteristic for Fe²⁺ state.
