Oxide electronics (or “oxitronics”) materials provide a plethora of possible applications and offer many opportunities for scientists to probe some of the most exciting and intriguing phenomena exhibited by oxide systems and oxide interfaces. Among these oxides, the ABO3 perovskite structure yields a fascinating class of materials, where almost all kinds of physical properties can be found (metallic, insulating, superconductivity, magnetism, ferroelectricity, etc…). For instance, BiFeO3 is exhibiting simultaneously ferroelectricity and antiferromagnetism, resulting in a rather unique room temperature multiferroic. The manganites, AMnO3, such as (La,Sr)MnO3 or CaMnO3, have also a very complex phase diagram encompassing ferromagnetism and metal-insulator transition. Furthermore, new properties are observed for heterostructures based on thin films of manganites, notably due to the presence of interfaces (with 3d perovskite such as BiFeO3, but also with 4d or 5d perovskites).
