Abstract We present a series of theoretical spin-polarized low-energy-electron-diffraction studies which explore the information that may be extracted from rotation curves. Here the polar angle of incidence of an unpolarized beam is held fixed, and the scattering plane is rotated so the azimuthal angle is scanned. The total intensity of the scattered beam is monitored, along with components of spin polarization in the scattered beam parallel and perpendicular to the scattering plane. Venus and collaborators have reported such data for the clean W(100) surfaces, and this surface covered by (ferromagnetic) Fe overlayers. We explore this system, focusing on the sensitivity of features in the rotation curves to aspects of surface geometry and surface magnetism. We find, for example, the polarization data to be very sensitive to interplanar spacings near the surface. {copyright} {ital 1996 The American Physical Society.}
