SPINTRONICS DEVICE, METHOD FOR ENHANCING PERFORMANCE OF SPINTRONICS DEVICE AND METHOD FOR MANUFACTURING THE SAME, AND MAGNETIC READ HEAD AND METHOD FOR MANUFACTURING THE SAME |
摘要 |
<P>PROBLEM TO BE SOLVED: To enhance device performance of a spintronics device and a magnetic read head, particularly Magneto-Resistance (MR) and Resistance-Area product (RA) ratios. <P>SOLUTION: One or more Magneto-Resistance Enhancing Layers (MRELs) are inserted into approximately a center of one or more of active layers (such as API layer 150, Free layers 170 and SIL layers) respectively. A MREL is a layer of a low band gap, high electron mobility semiconductor such as ZnO or a semimetal having those characteristics such as Bi. Furthermore, an interface(s) between the MREL and an active layer into which it has been inserted may be bridged by a thin layer of a highly conductive metal such as copper so as to ensure an ohmic contact across the full interface between the MREL and the active layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
