Abstract: In this thesis magnetic thin films with graded or tilted anisotropy are intensively studied for potential applications in spintronic devices. A continuum of stable remanent resistance states is realized in Co/Pd multilayers based on a perpendicularly magnetized pseudo spin valve (PSV). The Co/Pd multilayers have been deposited using magnetron sputtering. By varying the Co thickness in each repeating unit, a graded anisotropy through the multilayer is achieved. We then incorporate this graded ... more
