摘要:
A seedlayer structure for a high coercivity hard bias layer is disclosed, having at least one bi-layer seedlayer, including a CrMo layer, and a W layer fabricated on the CrMo layer. A hard bias layer is fabricated on the bi-layer seedlayer. Preferably, the seedlayer structure includes two bi-layer seedlayers, which including a first CrMo layer, a first W layer fabricated on the first CrMo layer, a second CrMo layer fabricated on the first W layer, and a second W layer fabricated on the second CrMo layer. Also disclosed is a high coercivity hard bias stack structure, a magnetic read head for a disk drive having a high coercivity hard bias stack structure and a method for fabricating a coercivity hard bias layer for a magnetic read head.
