具有非磁性种子层的装置及其形成方法
Abstract:
根据一个实施例，可配置一种装置，该装置包括：磁性材料的主极层；第二磁性材料层；设置在主极层和第二磁性材料层之间的第一非磁性材料间隙层；设置在主极层和第二磁性材料层之间的第二非磁性材料间隙层，其中第二非磁性材料间隙层直接毗邻第二磁性材料层设置。根据一个实施例，这允许该间隙充当第二磁性材料层的非磁性种子。根据一个实施例，这允许该间隙充当第二磁性材料层的非磁性种子。根据一个实施例，也可利用制造该设备的方法。
Abstract(English):

In accordance with one embodiment, an apparatus can be configured that includes a main pole layer of magnetic material; a second layer of magnetic material; a first gap layer of non-magnetic material disposed between the main pole layer and the second layer of magnetic material; a second gap layer of non-magnetic material disposed between the main pole layer and the second layer of magnetic material; and wherein the second gap layer of non-magnetic material is disposed directly adjacent to the second layer of magnetic material. In accordance with one embodiment, this allows the gap to serve as a non-magnetic seed for the second layer of magnetic material. In accordance with one embodiment, this allows the gap to serve as a non-magnetic seed for the second layer of magnetic material. In accordance with one embodiment, a method of manufacturing such a device may also be utilized.
