Preparation of Co2FeSn Heusler alloys by electrodeposition method

We propose a new method for preparing Heusler alloys on the basis of the electrodeposition. The alloy composition is controllable by the deposition potential. The composition ratio of (Co, Fe) and Sn is inversely proportional to the deposition potential. The effect of deposition potential on alloy composition, surface morphology, crystal structure, and magnetic properties of the samples was investigated. The (Co, Fe) vs. Sn alloy composition displayed an inverse dependence on the deposition potential. According to the magnetic measurement, the obtained Co2FeSn composition alloy showed ferromagnetic properties. The coercivity shows the minimum value in the stoichiometric samples.
