Spin transfer torque in nanopillar spin-valve with [CoFe/Pd]2 double free-layers

Jae-Chul Lee, / Chun-Yeol You, / Sug-Bong Choe, / Kyung-Jin Lee, / Kyung-Ho Shin,

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 I^CAP→P and I^CP→AP characterized by spin directions of three magnetic layers. Telegraph noise confirms the inversion in single domain model.
