“…Experimentally, they were prepared by DC-magnetron sputtering [6] and solid state reaction [2,3]. The available literature on electrodeposition in the Fe-Sn system showed no results for the preparation of Fe 5 Sn 3 and Fe 3 Sn [10,26,27]. The layers on the Hull cell samples deposited with 20 and 80 mA/cm 2 at different pH values were characterized by XRD diffraction.…”

Magnetic properties of the sustainable Fe–Sn alloys are already known. However, there is lack of information in the field of Fe–Sn electrodeposition. In the present study, a novel Fe(III)–Sn(II) electrolyte with tartaric acid as a single complexing agent is introduced. The influence of the pH and the current density on the structural properties of the Fe–Sn deposit was studied. The stability of the electrolytes as a main attribute of sustainability was tested. The ferromagnetic phases Fe5Sn3 and Fe3Sn were electrodeposited for the first time, and it was found that the mechanism of the Fe–Sn deposition changes from normal to anomalous at a pH value 3.0 and a current density of approximately 30 mA/cm2. A possible reason for the anomalous deposition of Fe–Sn is the formation of Fe-hydroxides on the cathode surface. Two electrolyte stability windows exist: The first stability window is around a pH value of 1.8 where bimetallic Fe–Sn tartrate complexes were formed, and second one is around a pH value of 3.5 where most of the Sn ions were present in the form of [Sn(tart)2]2− and Fe in the form of [Fe(tart)]+ complexes.

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.
