Antiparallel (AP) pinned spin valve sensor with specular reflection of conduction electrons

摘要

First and second specular reflector layers, which interface one another, are employed in a spin valve sensor with the first specular reflector layer located between a free layer and the second specular reflector layer. The first specular reflector layer is preferably copper (Cu) and the second specular reflector layer is preferably nickel oxide (NiO).
