Abstract

Neodymium p-toluenesulfonate was prepared and applied to the electrodepositon of neodymium-iron group alloy films. This salt has high solubility in DMF and can be dehydrated easily. Cyclic voltammograms of Pt electrode in (p-CH₃C₆H₄SO₃) 3Nd + MCl₂(M=Fe,Co,Ni) + DMF indicated that the neodymiun-iron group alloys can be elcetrodeposited from this medium, the Nd-Fe, Nd-Co and Nd-Ni films were obtained by electrolysis at constant potential. The Nd-Fe, Nd-Co and Nd-Ni films are amorphous in which the rare earth contents are in the range of 15 at%～60 at% as analyzed by XRD and EDS. The Nd content in the deposited film increases with the shift of cathode potential to the negative direction. The deposited Nd-Co film has good soft magnetic properites and its crystallization temperature was determined as 468.3 ℃.
