ABSTRACT:
A hard magnetic bias structure for a magnetic read head includes a seed layer made of CrMo, a hard bias magnet layer on top of the seed layer and made of CoPt, and a conducting layer below the seed layer. To lower the resistance of the structure while raising its magnetic coercivity, a first transition layer made of Ta and a second transition layer made of CoPt are disposed between the conducting layer and the seed layer.
