Abstract: A spin valve device containing a chromium or chromium and aluminum antiferromagnetic layer, which acts as a pinning layer for a magnetoresistive ferromagnetic layer, by exchange coupling. The antiferromagnetic layer has a tunable Neel temperature and anisotropy constant, and is corrosion resistant.
