  6. 4. Optical Spectroscopy on Correlated Electron Materials

    Author : Johan Bielecki; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dynamics; optical spectroscopy; colossal magnetoresistance; magnetism; transition metal oxides; high temperature superconductivity;

    Abstract : Strongly correlated materials poses a great challenge to our microscopic understanding of matter, mainly due to the inability of perturbative methods to predict the properties of such materials. This inability stems from strong correlations between electronic, lattice and spin degrees of freedom, leading to a variety of complex and exotic phenomena such as (unconventional) superconductivity, metal-insulator transitions, non-Fermi liquid behavior and colossal magnetoresistance.

  7. 5. Control of Defects and Subgrains in Epitaxial Perovskite Thin Films

    Author : Lars Ryen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thin film evolution; La0.70Ba0.30MnO3; epitaxial perovskite films; Keywords: TEM; dielectrics; EELS; SrTiO3; YBa2Cu3O7-x; superconductors; colossal magnetoresistance;

    Abstract : This work concerns the microstructure of epitaxial (001) perovskite thin films, studied by transmission electron microscopy (TEM), in particular high resolution TEM, electron energy-loss spectroscopy (EELS), and energy dispersive x-ray analysis. The perovskites exhibit interesting superconducting, dielectric, and magnetic properties. READ MORE
