Spin valve sensor with a spin filter and specular reflector layer |
摘要 |
A half metallic phase iron oxide (Fe3O4) layer is employed in either or both of a pinned layer structure and a free layer structure in a spin valve sensor for filtering minority electrons and reflecting majority electrons with respect to a spin scattering region for increasing the magnetoresistive coefficient dr/R of a spin valve sensor.
