Thin Magnetic Films.

This research involved studies of the magnetic properties of multilayered magnetic films and high quality thin films. 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 to measure the magnetic properties of the films and multilayers. The physics of the Giant Magnetoresistance GMR and multilayer exchange coupling was investigated by precise measurements of the GMR in both anisotropic magnetoresistance states. The effect of ion implanting, to cause point defects in the layers, was used to modify both the coupling between the layers and the GMR. MM
