Lower current-driven exchange switching threshold in noncollinear magnetic junctions under high spin injection

preprint2009arXivOpen access

Abstract

Current-induced switching is considered in a magnetic junction. The junction includes pinned and free ferromagnetic layers which work in the regime of the high spin injection. It is shown that in such a regime the exchange magnetization reversal threshold can be lowered up to two times when the axes of the layers are noncollinear.
