Orthogonal pinning of two ferromagnetic layers in a synthetic spin valve

A method for pinning synthetic antiferromagnet (SAF) based spin valves is presented, which allows pinning to be established perpendicular to the setting field H. As the SAF(AP1/Ru/AP2) magnetizes, its layer moments undergo a spin–flop transition for a magnetic field H=HSF and align with H for H=HSat...

Zusammenfassung:A method for pinning synthetic antiferromagnet (SAF) based spin valves is presented, which allows pinning to be established perpendicular to the setting field H. As the SAF(AP1/Ru/AP2) magnetizes, its layer moments undergo a spin–flop transition for a magnetic field H=HSF and align with H for H=HSat. The magnetization of layer AP1 is perpendicular to H for a field H=HGold. This field corresponds to the maximum giant magnetoresistance GMR on HSF
