Method and system for providing magnetic junctions usable in spin transfer torque applications utilizing interstitial glass-forming agent(s)

摘要

A magnetic junction and method for providing the magnetic junction are described. The method includes providing a free layer, providing a pinned layer and providing a nonmagnetic spacer between the free and pinned layers. The free layer is switchable between stable magnetic states using a write current passed through the magnetic junction. At least one of the step of providing the free layer and the step of providing the pinned layer includes depositing a magnetic layer; depositing an adsorber layer on the magnetic layer and performing at least one anneal. The magnetic layer is amorphous as-deposited and includes an interstitial glass-promoting component. The adsorber layer attracts the interstitial glass-promoting component and has a lattice mismatch with the nonmagnetic spacer layer of not more than ten percent. Each of the anneal(s) is at a temperature greater than 300 degrees Celsius and not more than 425 degrees Celsius.
