Abstract: In this thesis, we investigate the structural distortions appearing in three different kind of perovskite oxides that are fabricated as thin films following a chemical solution deposition process. In the first case, we study how the YBCO lattice is distorted around its most common defect, this is the Y124 intergrowth. Secondly, we investigate which structural mechanisms help to accommodate the strain generated by the substrate mismatch in nickelate thin films. Finally, we study how the spatial confinement influences both the physical and structural properties of La0.7Sr0.3MnO3/SrTiO3 heterostructures.
