Abstract
We have found that preoxidation of the bottom electrode prior to deposition of Al2O3 or MgO is very effective as a general approach to suppressing orange-peel coupling in magnetic tunnel junctions. When orange-peel coupling is suppressed, the hard-axis saturation field of the free layer is greatly reduced.
