Sd-exchange switching in magnetic junctions having non-pinned current carrier spins

摘要

Switching of magnetic junctions by spin-polarized current is considered with spin-transfer and spin-injection torques taking into account. In contrast with previous works, the mobile electron spins are assumed to be non-pinned both in collector and emitter layers. As a result, both parallel and antiparallel configurations can become unstable, depending on the layer parameters.
