Notes: A new general-purpose high-resolution electron energy loss spectrometer has been constructed and tested. Novel features of the electron optics include multichannel energy detection and tandem four-element zoom lenses that incorporate beam defining apertures. Compact design of the lenses permit scattering measurements in which the total scattering angle is less than 40°. This feature permits probing bulk phonon modes. The lens system permits electronic adjustment of the analyzer collection angle, and yields high transmission at retardation/acceleration ratios of 400:1. Performance characteristics include simultaneous detection of 50 energy channels at 4-meV energy resolution and target currents exceeding 2×10−10 A. Separate monochromator and analyzer goniometers permit access to out-of-plane scattering configurations which enables probing odd symmetry shear surface modes.

Notes: Abstract We describe magneto-optic Kerr effect studies of ultrathin Fe and Ni films on single crystal surfaces of Ag and Cu. Monolayer Fe films on Ag(100) exhibit the theoretically predicted spin-orbit anisotropy, but also yield some interesting discrepancies between behavior predicted by Kerr effect and by spin-polarized photoemission experiments. Layer-dependent studies of the magnetic moment of Ni on Ag(111) and Ag(100) suggest sp-d hybridization effects quench the first layer magnetic moment on Ag(111) but not on Ag(100). Temperature dependent studies of thin film magnetization obtained from Kerr effect measurements yield thickness dependent Curie temperatures, and critical exponents for several thin film systems.
