TLDR
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 is reported, which may be understood as a form of magnetic circular dichroism appearing in the uv photomission regime.Abstract:
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.read more
