Complex oxides represent a class of materials with several of exiting properties including magnetism, superconductivity or multiferroics.Thus, there are interesting for both fundamental research and applications.Using epitaxial strain, it is also possible in a thin film to modify the electronic properties as compare to bulk materials.While usually, the material is deposited on a single crystal to achieve the perfect epitaxy, it is also possible to synthesise the film on other type of substrate.
