Research focuses on structural properties and magnetic ordering in magnetic semiconductor, transition metal-, transition-metal oxide and/or rare-earth thin-film multilayers, patterned arrays, and nanoparticles with possible technological applications such as magnetic recording and cancer therapy. These materials are studied using both unpolarized and polarized beam neutron scattering techniques including reflectivity, SANS (small angle neutron scattering), and triple-axis spectroscopy. Current topics of interest include, but are not limited to, interparticle interactions among ferromagnetic nanoparticles, interfacial effects in multiferroics, depth-dependent anisotropy in perpendicular storage prototypes, exchange biasing in magnetic multilayers, and magnetic domain formation in buried magnetic layers. Results are correlated with models of the magnetic coupling, proximity effects, coherence range of the magnetism, finite size effects, effects of magnetostriction and anisotropy, and electronic effects.
