1. Raman Scattering and Neutron Diffraction Studies of Manganites and Cuprates
Sammanfattning : This thesis is devoted to experimental studies of two classes of strongly correlated transition metal oxides, namely cuprates and manganite perovskites. Manganites generally display complex phase diagrams, including the so-called colossal magnetoresistance effect. LÄS MER
2. Unifying first-principles and model approaches for strongly correlated materials : Interplay between long- and short-range correlations
Sammanfattning : In materials with open 3$d$ and 4$f$ shells the valence electrons are relatively localized around the atoms which leads to large electron-electron correlations. These, so called strongly correlated materials, exhibit many intriguing properties such as high $T_c$ superconductivity, colossal magneto-resistance and heavy fermion behaviour. LÄS MER
