| 摘要 |
A magnetic head with improved hard magnet properties includes a sensor stack structure and a multi-layered seed layer structure formed over crystalline materials of the sensor stack structure. The multi-layered structure has a first layer including chromium-molybdenum (CrMo); a second layer including nitrogenated nickel-tantalum (NiTa+N); and a third layer including chromium-molybdenum (CrMo). A hard bias layer formed over the multi-layered structure is preferably cobalt-platinum-chromium (CoPtCr). Methods of making the magnetic head are also described.
