Exchange bias effects along the out-of-plane direction have been investigated in arrays of 100nmnanostructures prepared on top of prepatterned substrates, consisting of a ferromagnetic [Pt/Co] multilayer with out-of-plane anisotropy exchange coupled to an antiferromagnetic IrMn layer. [...]

We present a study of exchange bias in ferromagnet/antiferromagnet/ferromagnet (FM/AFM/FM) trilayers, with in-plane and out-plane easy axes. Using element-specific x-ray magnetic circular dichroism, we demonstrate that simultaneous in-plane and out-of-plane exchange bias can be induced using a single antiferromagnet and zero field cooling, whereas field cooling only induces exchange bias to the layer with easy axis parallel to the cooling field.
