5. 3. Raman Scattering and Neutron Diffraction Studies of Manganites and Cuprates

   Author : Joakim Bäckström; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; high-T-c-superconductivity; Reverse Monte Carlo modelling; oxides; strongly correlated systems; manganites; cuprates; neutron diffraction; colossal magnetoresistance; Raman spectroscopy;

   Abstract : 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. READ MORE

6. 4. Pulsed laser deposition and nanofabrication of mesoscopic devices based on cuprates and manganites

   Author : Roberto de Andrés Prada; Vladimir M. Krasnov; Christian Bernhard; Taras Golod; Dag Winkler; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cuprates; manganites; pulsed laser deposition; nano-fabrication; heterostructures; fysik; Physics;

   Abstract : 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.
