Abstract
Description
Technical field
[0001] The invention belongs to the field of magnetic storage technology, and in particular provides a spin valve structure with a single magnetic domain structure current perpendicular to a plane configuration and a preparation method thereof. The spin valve has a high room temperature magnetoresistance effect and can be used in the next generation. The application of ultra-high storage density computer hard disk. Background technique
[0002] At present, in the widely used electronic computer technology, the storage of information is mainly realized through the computer hard disk. Therefore, as one of the key components of the computer hard disk, the read head of the hard disk plays a decisive role in the storage density of the hard disk. In today's computer hard disks, the "read" process uses a spin valve (hereinafter referred to as CIP-SPV) head with a current parallel to the plane configuration. With the application of the special dual-spin valve launched by ...
