1. Interfacial Microstructure of Lanthanum Manganites
Sammanfattning : .... LÄS MER
2. Sol−Gel Synthesis of CMR Manganites
Sammanfattning : The development of more advanced materials forms the basis of technological progress. One group of fascinating compounds with many potential applications in spintronic devices are the mixed-valence perovskite manganites. LÄS MER
3. 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
4. Pulsed laser deposition and nanofabrication of mesoscopic devices based on cuprates and manganites
Sammanfattning : This thesis explores the growth, the nano-fabrication and the study of the magneto-transport properties of Superconductor/Ferromagnet/Superconductor (SFS) structures from complex oxides such as the high Tc superconducting cuprate YBa2Cu3O7 (YBCO) and the ferromagnetic manganites La2/3Ca1/3MnO3 and La2/3Sr1/3MnO3 (LCMO and LSMO), deposited with the pulsed laser deposition (PLD) technique.The present work has been possible thanks to the collaboration between the “Magnetism and Superconductivity” Group at the University of Fribourg, in Switzerland, and the “Experimentell Kondenserade Materiens Fysik” Group at Stockholm University, in Sweden.

5. The role of interfaces in oxide thin films
Sammanfattning : The role of interfaces in oxide thin films has been investigated from a microstructural point of view. Thin films of manganites and titanates have been investigated by transmission electron microscopy (TEM). LÄS MER
