Abstract:
A method and system for providing a magnetic junction usable in a magnetic device are described. The magnetic junction includes a reference layer, a nonmagnetic spacer layer and a free layer. The nonmagnetic spacer layer is between the reference layer and the free layer. The free layer has a gradient in a magnetic ordering temperature such that a first portion of the free layer has a first magnetic ordering temperature higher than a second magnetic ordering temperature of a second portion of the free layer. The first portion of the free layer is closer to the reference layer than the second portion of the free layer. The magnetic junction is configured such that the free layer is switchable between stable magnetic states when a write current is passed through the magnetic junction.
