Abstract : This research involved studies of the magnetic properties of multilayered magnetic films. Ultra high vacuum sputtering techniques were utilized to prepare the films. The physics of the Giant Magnetoresistance (GMR) and multilayer exchange coupling was investigated by precise measurements of the GMR in both anisotropic magnetioresistance (AMR) states. It was found that the AMR affected the GMR by altering the electron mean free path. A Boltzmann equation approach was found to qualitatively predict the results.
