摘要：
A magnetoresistive spin-valve sensor is constructed to include a magnetic layer, a specular layer made of a metal oxide, a back layer made of Au, Cu, AuCu, AgCu, AuAgCu or an alloy thereof and interposed between the magnetic layer and the specular layer, and a metal layer disposed adjacent to the specular layer, opposite to the back layer, and made of a metal which improves GMR performance of the magnetoresistive spin-valve sensor.
