Abstract : This research involved studies of the magnetic properties of multilayered magnetic films and high quality thin. Both ultra high vacuum sputtering and molecular beam epitaxy techniques were utilized to prepare the films. Both electrical transport and magneto-optic effects were use measure the magnetic properties of the films. The primary focus during this year was to develop high quality trilayers consisting of a magnetic layer, nonmagnetic layer, and a magnetic layer. These structures are being developed to determine the scattering origin of the giant magnetoresistance phenomena. In addition, other investigations included the determination of the temperature dependence of the magnetic anisotropy energies of epitaxial iron films, the magnetization dynamics of thin films, and the general transport properties of multilayers. The transport effort utilized multilayers of magnetic and nonmagnetic metals to study the interfacial scattering. The combination of a magnetic and nonmagnetic metal i this work facilitates the origin of the scattering by use of the anisotropic magnetoresistance.
