本文报道了利用圆极化vuv同步辐射，观察了自旋轨道相互作用对流动铁磁体（fcc钴）角分辨光发射的影响。发现Co 3波段区域的光电子能谱与样品磁化和光子自旋的相对取向有关。这种效应可以理解为一种形式的磁圆二色性出现在紫外线的光度制度。它可以用来研究铁磁体中的磁性现象，而不需要进行明确的自旋极化分析。
We report the observation of effects due to spin-orbit interaction in angle-resolved photoemission from an itinerant ferromagnet (fcc cobalt) using circularly polarized vuv synchrotron radiation. The photoelectron spectra of the Co 3d-band region are found to depend on the relative orientation of the sample magnetization and the photon spin. This effect may be understood as a form of magnetic circular dichroism appearing in the uv photomission regime. It may be used to investigate magnetic phenomena in ferromagnets without performing an explicit spin-polarization analysis.
