SPEES studies involve the energy- and spin-analysis of electrons emitted normal to the surface of a sample during grazing angle ion-surface reflection. The information obtained from the emitted electrons allows us to characterize the surface electronic, magnetic, and chemical structure, as well as processes occurring during ion-surface interactions. Studies were made on Ni(110) surfaces bombarded with H$\sp+$ and He$\sp+$ ions at an energy of 25 keV. Electron intensity distributions exhibit distinct features that are strikingly different from large-angle ion- and electron-induced electron emission spectra. Polarization data obtained allow us to unravel various physical processes occurring at the surface. Studies made on PtMnSb samples again show distinct and pronounced peaks and features which are more apparent in SPEES spectra than in any other spectroscopy. The studies made on these samples, using SPEES, show the power of this new spectroscopy to characterize and understand particle-surface interaction processes previously not well understood. 93 p. application/pdf eng Condensed matter physicsEngineeringMaterials science Surface magnetism study of nickel(110) and platinum-manganese-antimony using spin polarized electron emission spectroscopy (SPEES) Thesis Text Physics Natural Sciences Rice University Doctoral Doctor of Philosophy Waters, Kelley Lyle.
