The main focus of our research is in the static and dynamic properties of superconducting vortices. We employ both electronic and magnetic measurements. In particular, we use scanning Hall probe microscopy to image vortices in thin films.

Our group carries out optical, x-ray, and electronic measurements on a wide variety of materials under pressure. We employ diamond-anvil and gas-pressure cells, and we have constructed a unique instrument for simultaneous application of hydrostatic and uniaxial stress.

We carry out neutron-scattering studies of materials at Los Alamos and Argonne National Laboratories. Our principal interest is in crystal-field effects in rare earth and actinide atoms, which are associated with interesting magnetic phenomena in compounds containing such atoms.

Our group investigates the elastic properties of materials using resonant ultrasound spectroscopy. This technique enables full determination of elastic constants by a single measurement, and it can be carried out on small samples. Recent objects of study include hydrogen-storage materials, nanocrystalline materials, and quasicrystals.

Our group is is engaged in a variety of basic and applied research that ranges from the fundamental understanding of magnetic order to the study of materials and device structures for information storage, radar, and high frequency signal processing applications.

Our group does detailed experimental studies and modeling of photovoltaic devices, particularly those based on thin-film, polycrystalline CuInS and CdTe. Much of our effort is devoted to quantifying specific mechanisms for loss of efficiency.

The research of our group is focused on spin wave dynamics in magnetic films, solitons and chaos, parametric pumping; magnetic nanoparticles, nanocomposities, and nanostructures; microwave and millimeter wave magnetic materials and devices.
