SmCo alloys have attracted attention for their high Curie temperature, magnetic anisotropy and relatively high saturation magnetization. Because of the very negative reduction potential of Sm in aqueous solution, its electrodeposition is problematic due to strong hydrogen evolution at the cathode surface. Deep eutectic solvent solution of 1 choline chloride: 2 ethylene glycol is studied as alternative solution to aqueous solvents for the electrodeposition of SmCo alloys. This study is focused on the deposition process of the alloy; variable Sm% contents are obtained depending on the experimental conditions e.g. bath formulation, deposition voltage and stirring condition.

Abstract

SmCo alloys have attracted attention for their high Curie temperature, magnetic anisotropy and relatively high saturation magnetization. Because of the very negative reduction potential of Sm in aqueous solution, its electrodeposition is problematic due to strong hydrogen evolution at the cathode surface. Deep eutectic solvent solution of 1 choline chloride: 2 ethylene glycol is studied as alternative solution to aqueous solvents for the electrodeposition of SmCo alloys. This study is focused on the deposition process of the alloy; variable Sm% contents are obtained depending on the experimental conditions e.g. bath formulation, deposition voltage and stirring condition.
