  3. 3. Structure and Dynamics in Transition Metal Perovskites — An Optical Spectroscopy Study

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johan Bielecki; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multiferroics; colossal magnetoresistance; magnetism; proton-conduction; spin-state transition; structure; Ultrafast spectroscopy; high temperature superconductivity; dynamics; Raman;

    Abstract : Transition metal oxides with the perovskite structure exhibit a vast number of exotic properties due to the large number of competing degrees of freedom at the Fermi surface. Together with couplings between and correlations within these degrees of freedom, this class of materials is of high interest from both a practical and theoretical point of view. READ MORE

  4. 4. On Model Libraries for Thermo-hydraulic Applications

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)
