Aim is to show how to make neodymium iron alloys available for MEMS process by electroplating used for permanent magnetic material. Because of the low electrochemical potential of neodymium, three different deposition methods were investigated: Electroplating from aqueous solvent, from non-aqueous solvent and molecular plating. All results shows as brittle deposited film. Due to the high oxidation behavior of neodymium a high amount of oxygen could be observed, which indicates a complete oxidized film.
