摘要：

The atomic structure across the annealed Ni/Mn/NiFe exchange coupled interface has been studied. NiMn grows epitaxially on NiFe (111) according to a cube on cube orientation relationship. This yields a semi-coherent interface which is made up of atomic ledges. Due to the stabilizing effect of fee NiFe, it was found that the NiMn crystal cannot attain the ordered L1(0) structure thus holding down the strength of the exchange bias field. However, twinning at the interface seemingly helps to assist NiMn ordering.
