Abstract: A data writer can be configured with at least a write pole separated from a front shield by a non-magnetic gap layer. The front shield may consist of at least a seed layer and a shielding layer with the shielding layer having an easy axis coercivity along a first direction of 4 Oe or more and a hard axis coercivity along a second direction of 0.5 Oe or more.
Abstract translation: 数据写入器可以被配置成具有至少一个与前屏蔽件由非磁隙层分离的写入极。 前屏蔽可以由至少种子层和屏蔽层组成，屏蔽层沿着第一方向为4Oe以上具有容易的轴矫顽力，并且沿着第二方向具有0.5Oe以上的硬轴矫顽力。

Abstract: A method of forming a magnetic element. The method includes cooling a substrate to a cryogenic temperature. The method further includes depositing a magnetic layer with a grain refining dopant on the substrate. The magnetic layer with the grain refining dopant deposited on the substrate cooled to the cryogenic temperature has a magnetic moment that is greater than 2 Tesla and very soft magnetic properties.

Abstract: A method of forming a magnetic recording head. The method includes depositing a sacrificial metal alloy layer, which is wet etchable and has a moderate mill resistance, over a substrate. The method also includes depositing a write pole layer over the sacrificial metal alloy layer. The write pole layer has a bottom surface and a top surface opposite the bottom surface. A portion of the bottom surface of the write pole layer is in contact with the sacrificial metal alloy layer.
