Abstract

We studied spin transfer torque in nanofabricated pillars with [CoFe/Pd]2 double free-layers. This sample showed various spin transfer switching properties as a function of external magnetic fields. We report the first observation of two-step switching and the inversion of IC AP→P and ICP→AP characterized by spin directions of three magnetic layers. Telegraph noise confirms the inversion in single domain model.
