Recent developments in the fi eld of thin-fi lm growth technologies have allowed control at an atomic level of deposited layers, thus opening new perspectives in the fi eld of engineering of multilayers and heterostructures based on complex oxides. In particular, it is expected that oxide heterostructures, with almost ideal interfaces, may lead to interesting artifi cial materials with novel properties. Artifi cial thin-fi lm oxide structures make the already complex individual bulk properties even more interesting through their interaction at the interface. Following such an approach, a number of heterostructures have been tailored which show extraordinary properties that do not belong to the individual layers. These range from superconductivity at the interface between nonsuperconducting layers to high-mobility 2D conductivity at the interface between insulating oxides.[2,3] The number of possible combinations of these oxides is enormous, and the potential for novel behavior having practical applications represents a strong motivation for this research.
