Research Interests:

The focus on materials research has changed dramatically over the past decade, as findings demonstrated the relevance length- and timescales have on structure-property relationships. To fully understand the coupling mechanisms, microstructures and nature of nanometer scaled materials. Professor Louca’s group probes structures and dynamics at the smallest scales possible using scattering techniques, and combined with studies of bulk properties, they are directly linked to materials functioning. They also elucidate important details of the thermodynamics, atomistic and magnetic effects. The group focuses primarily on complex oxides, insulating and metallic, that play a central role in many areas including magnetism, superconductivity, ferroelectricity and magnetoresistivity. These exhibit unique structure-property relationships germane to condensed matter and to the materials physics, and have the potential for technological applications. The group is involved with the synthesis and property measurements at the University and frequently visits national laboratories for the neutron and x-ray scattering characterization.
