摘要：
We have developed a new spin-polarized photoemission spectrometer combined a commercial hemispherical electron energy analyzer with an electron spin-polarimeter employing the very low energy electron diffraction (VLEED) at a Fe(001)p(1×1)-O surface. The new polarimeter has realized the effective Sherman function of 0.40 and the figure of merit of 1.9×10-2, which is approximately two orders of magnitude higher than that expected with a compact Mott scattering spin-polarimeter. The new system enabled us to measure spin- and angle-resolved photoemission spectra with high energy and momentum resolutions.
