本文报道了多层膜边缘的X射线磁性圆二色谱测量结果。提供了两极分化的明确证据。其感生磁矩很小，约比Co/Pt多层膜小一个数量级。轨道磁矩与自旋磁矩之比为。根据第一原理计算，讨论了多层膜的铁磁响应及其在解释多层膜磁光光谱中的作用。
X-ray magnetic circular dichroic measurements at theedges ofinmultilayers are reported. A clear evidence forpolarization is provided. The induced magnetic moment ofis very small, about one order of magnitude smaller than in Co∕Pt multilayers. The ratio of orbital-to-spin magnetic moment ofis found to be. The ferromagnetic response ofand its role on the interpretation of the magneto-optic spectra ofmultilayers are discussed with respect tofirst principlecalculations.
