Magnetic layered material, and magnetic sensor and magnetic storage/read system based thereon |
摘要 |
A ferromagnetic and antiferromagnetic material having a high exchange coupling and a high thermal stability, and a magnetic storage system using this material which has excellent reliability and recording density, and a magnetoresistive storage/read separation head having a high sensitivity and a low noise property. The magnetic storage/read system of the invention mounts a magnetoresistive head using a chromium-manganese antiferromagnetic layer/a cobalt alloy layer as a pinning layer or the longitudinal bias layer of the spin-valve type magnetoresistive layered film.
