Abstract

The micromolding technique has been successfully applied to samarium–cobalt (SmCo) films electrodeposited in an aqueous solution. After optimization of the deposition conditions in a Hull cell, taking into account the supplying mode, the pulse time and the addition of supporting electrolyte, films with thickness between 1 and 1.5 μm have been patterned in 1 mm × 1 mm squares. Is has been found that high Sm/(Sm + Co) ratio can be obtained in direct current mode, with or without supporting electrolyte. In addition, the micromolding process reduces the contamination in oxygen due to oxidation and/or incorporation of precipitates, from 20 to 30 % in the Hull cell to 10–15 % in the pattern.
