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 focus was determination of the temperature dependence of the magnetic anistropy energies of epitaxial iron films, the magnetization dynamics of thin films, and the transport properties of multilayers. In the anisotropy energy work the effects of interfacial strain and morphology were the focus. The dynamics effort has recently provided a model for slow dynamic systems. The transport effort utilized multilayers of magnetic and nonmagnetic metals to study the interfacial scattering. The combination of a magnetic and nonmagnetic metal in this work facilitates the origin of the scattering by use of the anisotropic magnetoresistance.
