METHOD AND SYSTEM FOR PROVIDING TOP PINNED LAYER PERPENDICULAR MAGNETIC ANISOTROPY MAGNETIC JUNCTION USABLE IN SPIN TRANSFER TORQUE MAGNETIC RANDOM ACCESS MEMORY APPLICATIONS

摘要

A method for providing a magnetic junction usable in a magnetic device and the magnetic junction are described. A free layer and nonmagnetic spacer layer are provided. The free layer and nonmagnetic spacer layer are annealed at an annealing temperature of at least three hundred fifty degrees Celsius. A pinned layer is provided after the annealing step. The nonmagnetic spacer layer is between the pinned layer and the free layer. The magnetic junction is configured such that the free layer is switchable between a plurality of stable magnetic states when a write current is passed through the magnetic junction.;COPYRIGHT KIPO 2015
