Abstract
An ultrahigh differential current perpendicular to the plane dual spin valve read head with high pinning stability. The high pinning stability may be achieved using the same anti-ferromagnetic materials for two spin valves by introducing a double synthetic anti-ferromagnetic structure in one of the two spin valves.
