Spin polarization and temperature effects in reflection diffraction from W(001)
Journal Article

· Phys. Rev. Lett.; (United States)
Simultaneous low-energy electron diffraction (LEED) and electron-spin polarization measurements have been made on clean W(001) for the first time at a high angle of incidence (47.5/sup 0/) wih a surface azimuth of 50/sup 0/. Polarization peaks ranging from +15% to -27% have been observed and occur at energies where the LEED intensities are close to a minimum. After a cleaning flash, effects ascribed to specimen cooling caused changes with time in LEED intensities but not in spin polarization. Reasons are discussed.
