Title:
スピントロニクス素子およびその製造方法、ならびに磁気読み取りヘッドおよびその製造方法
Document Type and Number:
Japanese Patent JP5840739
Kind Code:
B2
Abstract:
The performance of an MR device has been improved by inserting one or more Magneto-Resistance Enhancing Layers (MRELs) into approximately the center of one or more of the magnetic layers such as an inner pinned (AP1) layer, spin injection layer (SIL), field generation layer (FGL), and a free layer. An MREL is a layer of a low band gap, high electron mobility semiconductor such as ZnO or a semimetal such as Bi. The MREL may further comprise a first conductive layer that contacts a bottom surface of the semiconductor or semimetal layer, and a second conductive layer that contacts a top surface of the semiconductor or semimetal layer.
