Research Interests

omplex oxides exhibit fascinating electronic and structural properties. These quantum materials are at the frontier of research in condensed matter physics since they provide myriad possibilities to discover and study novel fundamental phenomena and phases, including new kinds of magnetic and charge order, as well as unconventional superconductivity. Moreover, many complex oxides exhibit properties that have potential applications in technology.

Materials preparation is the heart of any successful materials physics endeavor. Our group’s research involves the growth of high-quality single crystals using state-of-the-art techniques. The experimental techniques of X-ray and neutron scattering play invaluable roles in materials science and condensed matter physics, as they provide essential structural and magnetic information about new phases of matter and the transitions between them. We pursue such scattering experiments at leading facilities in the US and abroad. Our research furthermore involves non-linear magnetic susceptibility and charge transport experiments, including measurements at high-field magnet laboratories. In addition to our own experiments, the crystals grown in our lab enable measurements by numerous scientists around the world who use complementary experimental techniques.

Our research is supported by the Department of Energy’s Office of Basic Energy Sciences and by the National Science Foundation.
