摘要：
In order to directly investigate the energy band dispersion and the origin of the magnetic moment in intercalation compounds FexTiS2, we have measured the angle-resolved photoemission (ARPES) spectrum and the magnetic circular dichroism (MCD) of the soft X-ray core absorption (XAS) spectra using a synchrotron light source. The energy band dispersion is clearly observed in the Ti 2p(3/2)(e(g)) on-resonance ARPES spectra. In the Ti 2p XAS spectra the MCD is clearly seen, suggesting that a magnetic moment is induced on the Ti atom through the hybridization with the Fe 3d orbitals. We quantitatively estimate the orbital and spin magnetic moments of the Fe and Ti atoms by using the magneto-optical sum rules.
