摘要： A laminated main pole layer is disclosed in which a non-AFC scheme is used to break the magnetic coupling between adjacent high moment layers and reduce remanence in a hard axis direction while maintaining a high magnetic moment and achieving low values for Hch, Hce, and Hk. An amorphous material layer with a thickness of 3 to 20 Angstroms and made of an oxide, nitride, or oxynitride of one or more of Hf, Zr, Ta, Al, Mg, Zn, or Si is inserted between adjacent high moment stacks. The laminated structure also includes an alignment layer below each high moment layer within each stack. In one embodiment, a Ru coupling layer is inserted between two high moment layers in each stack to introduce an AFC scheme. An uppermost Ru layer is used as a CMP stop layer. A post annealing process may be employed to further reduce the anisotropy field (Hk).

摘要： Improved magnetic devices have been fabricated by replacing the conventional seed layer (typically Ta) with a bilayer of Ru on Ta. Although both Ru and Ta layers are ultra thin (between 5 and 20 Angstroms), good exchange bias between the seed and the AFM layer (IrMn about 70 Angstroms thick) is retained. This arrangement facilitates minimum shield-to-shield spacing and gives excellent performance in CPP, CCP-CPP, or TMR configurations.
摘要翻译：已经通过用Ta上的Ru的双层代替常规种子层（通常为Ta）来制造改进的磁性器件。虽然Ru和Ta层都是超薄的（5到20埃之间），但保留种子和AFM层之间良好的交换偏差（约为70埃的IrMn）。这种安排有助于最小的屏蔽间隔，并在CPP，CCP-CPP或TMR配置中提供出色的性能。

摘要： A process for forming the write pole of a PMR head is described. This write pole is symmetrically located relative to its side shields, This is accomplished, not through optical alignment, but by coating the pole with a uniform layer of non-magnetic material of a predetermined and precise thickness, followed by the formation of the shield layer around this.
摘要翻译：描述了用于形成PMR头的写入极的过程。该写入极相对于其侧屏对称地定位，这不是通过光学对准而是通过用预定和精确厚度的均匀的非磁性材料层涂覆极，然后形成屏蔽层围绕这一点。
