Magnetic properties of CoZrNb thin films deposited on amorphous SmCo

Amorphous CoZrNb thin films mere deposited on amorphous SmCo thin films. The amorphous SmCo layer generated magnetic bias field for the soft film, and this bias field was increased as the length of easy direction was reduced. The bias field of 60Oe was measured for the sample with the dimension 3 mm/spl times/0.5 mm. The magnetization process of the biased soft film was different from that of a single layer film.
