XENON ON FERROMAGNETIC SURFACES - A SPIN-RESOLVED PHOTOEMISSION STUDY

摘要

Physisorbed xenon on magnetized iron (110), iron (100), and cobalt (0001) films has been investigated by means of spin- and angle-resolved photoelectron spectroscopy with unpolarized light. Spin-resolved spectra revealed different energy positions of the 5p(3/2) and 5p(1/2) adsorbate levels in the majority and minority spin channels. The splitting shows a significant angle dependence including a sign reversal, with the maximum occurring in normal emission. This behavior can be qualitatively explained by a spin-dependent pinning of adsorbate and substrate bands. [References: 56]
