Abstract
Material stacks for perpendicular spin transfer torque memory (pSTTM) devices, pSTTM devices and computing platforms employing such material stacks, and methods for forming them are discussed. The material stacks include a cladding layer of predominantly tungsten on a protective layer, which is in turn on an oxide capping layer over a magnetic junction stack. The cladding layer reduces oxygen dissociation from the oxide capping layer for improved thermal stability and retention.
