Tin-nickel-iron (Sn-Ni-Fe) ternary alloys have been successfully prepared for the first time by electrochemical deposition. Fe-57 and Sn-119 conversion electron Mossbauer and PXRD investigations of these alloys showed that the alloys were dominated by new metastable phases which do no occur in the thermally prepared alloys and are not to be found in the corresponding equilibrium phase diagram. Essentially these ternary alloys proved to be amorphous and ferromagnetic. (C) 2010 Elsevier B.V. All rights reserved.
