    摘要: A thin film magnetic head includes an upper shield section, a lower shield section and a magnetoresistance device section between the upper shield section and the lower shield section. The magnetoresistance device section is connected to the upper shield section and the lower shield section through conductive layers. Current flows through the magnetoresistance device section via the upper shield and the lower shield.

    摘要: The magnetoresistive device of the present invention includes: at least two magnetic layers stacked via a non-magnetic layer therebetween; and a metal reflective layer of conduction electrons formed so as to be in contact with at least one of outermost two layers of the magnetic layers. The metal reflective layer is in contact with one surface of the outermost magnetic layer which is opposite to the other surface of the outermost magnetic layer in contact with the non-magnetic layer. The metal reflective layer is likely to reflect conduction electrons while maintaining a spin direction of electrons.
