METHOD AND SYSTEM FOR PROVIDING A BORON-FREE MAGNETIC LAYER IN PERPENDICULAR MAGNETIC JUNCTIONS

METHOD AND SYSTEM FOR PROVIDING A BORON-FREE MAGNETIC LAYER IN PERPENDICULAR MAGNETIC JUNCTIONS

A magnetic junction and method for providing the magnetic junction are described. The method includes providing a pinned layer, a nonmagnetic spacer layer and a free layer switchable between stable magnetic states. The nonmagnetic spacer layer is between the pinned and free layers. Providing the pin...

description A magnetic junction and method for providing the magnetic junction are described. The method includes providing a pinned layer, a nonmagnetic spacer layer and a free layer switchable between stable magnetic states. The nonmagnetic spacer layer is between the pinned and free layers. Providing the pinned layer and/or providing the free layer includes cooling a portion of the magnetic junction, depositing a wetting layer while the portion of the magnetic junction is cooled, oxidizing/nitriding the wetting layer and depositing a boron-free magnetic layer on the oxide/nitride wetting layer. The portion of the magnetic junction is cooled to within a temperature range including temperature(s) not greater than 250 K. The wetting layer has a thickness of at least 0.25 and not more than three monolayers. The wetting layer includes at least one magnetic material. The boron-free magnetic layer has a perpendicular magnetic anisotropy energy greater than an out-of-plane demagnetization energy.
