Research Interests
Developing an understanding of the magnetic properties of materials. This includes interfacing theoretical and experimental studies of magnetic and superconducting materials.
Flux pinning in high temperature superconductors.
Understanding the fundamental magnetic properties of magnetic surfaces, interfaces and multilayers.
Continuing interest in the magnetic properties of icosahedral structures includes the study of magnetic quasicrystals and the magnetic and superconducting properties of fullerenes.
Study of carbon-coated magnetic nanocrystals produced by the Kratschmer-Huffman carbon arc method and fine particle magnetism in the same. This lead to studies of the plasma torch synthesis of metallic, C-coated, oxide, carbide and nitride nanoparticles.
Reactive gas plasma torch synthesis to produce nanocrystalline ferrite materials for high frequency applications. The surface structure, and its influence on properties, is being studied in faceted ferrite nanoparticles.
Active research in bulk and thin film soft magnetic metallic nanocomposites. These have excellent soft magnetic properties as measured by the figures of merit of combined induction and magnetic permeability.
High temperature magnetic properties including the study of HITPERM nanocomposites with a'(B2)-FeCo formed with significantly improved high temperature magnetic properties.
Research in rapid solidification processing, plasma synthesis of magnetic nanoparticles and characterization of magnetic properties as a function of field, temperature and frequency.
