Abstract

Spin- and angle-resolved photoelectron spectrometer using a laser light of 6.994 eV as a photon source has been developed at Laser and Synchrotron Research Center in Institute for Solid State Physics. The spectrometer consists of a high-energy resolution photoelectron analyzer and two high-efficient spin detectors associating very low energy electron diffraction, which allows us to analyze the three-dimensional spin polarization of electrons with high-energy and -angular resolutions. Fermi surface mapping and spin- and angle-resolved photoelectron spectroscopy of a surface state of Bi(111) have been performed to demonstrate the performance of the new spectrometer.
