磁性圆X射线二向色性测量在Co ${\mathit{L}}_{3}$和${\mathit{L}}_{2}$边缘的Co/Pd多层膜给出了第一个实验证据大大增强的轨道时刻相比，在体Co，证实了最近的理论预测。我们的结果还表明，在一般情况下，有没有简单的二色性信号之间的关系，无论是自旋矩或总的时刻。通过一个简单的模型计算验证了这一点。
Magnetic circular x-ray dichroism measurements at the Co ${\mathit{L}}_{3}$ and ${\mathit{L}}_{2}$ edges in Co/Pd multilayers give first experimental evidence for a greatly enhanced orbital moment compared to that in bulk Co, confirming recent theoretical predictions. Our results also show that, in general, there is no simple relationship between the dichroism signal and either the spin moment or the total moment. This is verified by a simple model calculation.
