Branton J. Campbell
Professor of Physics
CURRENT RESEARCH INTERESTS: Group-theoretical analysis of structural order parameters (e.g. atomic displacements, site occupancies, magnetic moments, lattice strains) arising from phase transitions at commensurate or incommensurate wave vectors. Symmetry in periodic and modulated crystals, both magnetic and non-magnetic. Experimental x-ray and neutron scattering. Diffuse scattering studies of nanoscale structure-property relations in complex oxides (high-Tc cuprates, colossal magnetoresistive manganites, relaxor ferroelectrics, and open-framework materials).
