Abstract:
A magnetic device and method for providing the device are described. The magnetic device includes magnetic junction(s) and spin-orbit interaction active layer(s) adjacent to the magnetic junction free layer(s). The magnetic junction includes free and pinned layers separated by a nonmagnetic spacer layer. The free layer is switchable between stable magnetic states. Providing the pinned and/or free layer(s) includes providing a magnetic layer including a glass-promoting component, providing a sacrificial oxide on the magnetic layer, providing a sacrificial layer on the sacrificial oxide and performing anneal(s) of the magnetic layer, the sacrificial oxide layer and the sacrificial layer at anneal temperature(s) greater than 300 degrees Celsius and not exceeding 475 degrees Celsius. The magnetic layer is amorphous as-deposited but is at least partially crystallized after the anneal(s). The sacrificial layer includes a sink for the glass-promoting component. The sacrificial layer and the sacrificial oxide are removed after the anneal(s).

Claim (Index 20):
A memory magnetic junction residing on a substrate and comprising:\n a plurality of magnetic storage cells, each of the plurality of magnetic storage cells including at least one magnetic junction, the at least one magnetic junction including a free layer, a nonmagnetic spacer layer and a pinned layer, the nonmagnetic spacer layer residing between the pinned layer and the free layer, the free layer being switchable between a plurality of stable magnetic states when a write current is passed through the magnetic junction, the free layer having a perpendicular magnetic anisotropy energy greater than an out-of-plane demagnetization energy, at least one of the pinned layer and the free layer including a crystalline magnetic layer having a body-centered cubic crystal structure and a (100) orientation, the at least one of the pinned layer and the free layer including at least one of MgO, Ta and W; at least one spin-orbit interaction (SO) active layer adjacent to the free layer of the each of the plurality of magnetic junctions, the at least one SO active layer carrying a current in-plane, the at least one SO active layer exerting a SO torque on the free layer due to the current passing through the at least one SO active layer, the free layer being switchable between a plurality of stable magnetic states using the SO torque.
