The basic electrodeposition behavior of Dy-Fe was investigated and a rectangular pulse electrodeposition technique was applied to this system. The current efficiency of DC electrodeposition decreased at values over 50A m-2, but electrodeposition with rather high current efficiency was possible in the pulse current density range between 100 and 250A m-2. A predominant pulse effect was observed at a duty cycle [on time/[on time+off time]] below 50%. A smooth, bright and amorphous film was obtained using the pulse technique.
