Mössbauer and XRD study of novel quaternary Sn-Fe-Co-Ni electroplated alloy

Abstract

A constant current technique electrochemical deposition was used to obtain quaternary alloys of Sn -Fe-Co-Ni, which to date have not been reported in the literature, from a gluconate electrolyte. For the characterization of electroplated alloys 57 Fe and 119 Sn conversion electron Mössbauer spectroscopy (CEMS) and XRD were used. XRD revealed the amorphous character of the novel Sn-Fe-Co-Ni electrodeposited alloys. 57 Fe Mössbauer spectrum of quaternary deposit displayed a magnetically split sextet with broad lines typical of iron bearing ferromagnetic amorphous alloys. Magnetically split 119 Sn spectra reflecting a transferred hyperfine field were also observed. New quaternary Sn-Fe-Co-Ni alloys were successfully prepared.

Effect of Cobalt on the Microstructure of Fe-B-Sn Amorphous Metallic Alloys

“…There are, however, only a few studies related to Fe-based MGs that also contain Sn [20,21], presumably due to problems with the production of amorphous structures with higher tin contents. 119 Sn MS was applied to mechanically alloyed Fe-Sn alloys [22,23], to electrodeposited amorphous alloys [24,25], to amorphous Mn-Sn [26], or to Ni-Mn-Sn metamagnetic alloys [27].…”
