Abstract Details

2003, Master of Science, Miami University, Physics.
This account investigates the anisotropy of magnetic thin films of permalloy, Ni80Fe20, which contain periodic arrays of lithographically defined antidot holes. These samples are studied by means of magneto-optical Kerr effect (MOKE). Detailed in-plane anisotropy data is given which indicates that the symmetry present in the hole pattern controls the formation of easy and hard axes in the samples. As well, an atomic force microscope (AFM) and magnetic force microscope (MFM) analysis is undertaken. Finally, OOMMF, a micromagnetic simulation program, is used to theoretically verify our experimental MOKE results, as well as to simulate the remnant field domain structure of an antidot sample.
