利用光电子显微术和X射线磁圆二色性相结合的方法，获得了在Cu（001）单晶上外延生长的Co/FeMn和FeMn/Co双层膜的元素选择性磁畴图像。与铁磁性Co的接触导致观察到Fe和Mn中的净磁矩，独立于FeMn薄膜的顺磁性或反铁磁性状态。只有一小部分的这一时刻可能介导的界面处的磁相互作用，从而负责交换偏置效应。
Using photoemission electron microscopy in combination with x-ray magnetic circular dichroism, element selective magnetic domain images have been obtained from single-crystalline Co/FeMn and FeMn/Co bilayers epitaxially grown on a Cu(001) single crystal. The contact with ferromagnetic Co leads to the observation of a net magnetic moment in Fe and Mn, independently of the paramagnetic or antiferromagnetic state of the FeMn thin films. Only a small fraction of this moment might mediate the magnetic interaction at the interface, and thus be responsible for the exchange bias effect.
