Applications of Polarized Electron Sources Utilizing Optical Orientation in Solids

January 1, 1984

Author(s)

Daniel T. Pierce, Robert Celotta

Spin-Polarized Electron Scattering Studies of the Ferromagnetic Glass, Fe 81.5 B 14.5 Si 4

January 1, 1984

Author(s)

John Unguris, Daniel T. Pierce, Robert Celotta

Low-energy [(20-500)-eV] spin-polarized electrons were used to probe the magnetic surface properties of the ferromagnetic metallic glass Fe 81.5B 14.5Si 4. The spin-independent intensity and the spin-dependent asymmetry of the elastic scattering were

Spin-Polarized Inverse Photoelectron Spectroscopy of Solid Surfaces: Ni(110)

October 4, 1982

Author(s)

John Unguris, A Seiler, Robert Celotta, Daniel T. Pierce, Philip Johnson, N. Smith

Inverse photoemission spectra have been measured on Ni(110) at 9.7-eV photon energy with a spin-polarized electron source. Consistent with band theory, a d-band-derived peak is observed just above the Fermi level that corresponds to transitions to minority

Spin-Dependent Elastic Scattering of Electrons from a Ferromagnetic Glass Ni 40 Fe 40 B 20

September 1, 1982

Author(s)

Daniel T. Pierce, Robert Celotta, John Unguris, H Siegmann

The dependence of the elastic scattering of electrons on the relative direction of the spin of the incident electron with respect to the magnetization of the ferromagnetic glass Ni 40Fe 40 B 20 was measured at various energies, angles, and temperatures. We

Spin and Energy Analyzed Secondary Electron Emission from a Ferromagnet

July 5, 1982

Author(s)

John Unguris, Daniel T. Pierce, A Galejs, Robert Celotta

Measurements are presented of the energy dependence of the spin polarization of low-energy (0.5-25 eV) secondary electrons when a 500-eV primary beam is incident on an iron-based ferromagnetic glass. The polarization of the lowest-energy electrons is found

Direct Verification of Hydrogen Termination of the Semiconducting Diamond (111) Surface

July 1, 1982

Author(s)

B Waclawski, Daniel T. Pierce, Nils Swanson, Robert Celotta

Low-energy, high-resolution electron energy loss spectroscopy has been used to identify the vibrational modes of hydrogen on the semiconducting diamond surface providing the first direct evidence that the (111) 1X1 surface is terminated by hydrogen. The
