Perovskite-type oxides are a large class of materials with many interesting properties, including piezo- and pyroelectricity, mixed ionic-electronic conductivity and high catalytic activity. Thus, there is a wide range of applications, for example the use as sensors or as electrode materials in solid oxide fuel cells. Their general chemical formula is ABO3, with two different cations A (bigger) and B (smaller). The ideal structure is cubic, but it is often distorted as can be seen for La0.9Ca0.1FeO3 (figure 1). The high versatility of the material class is due to the possibility of adjusting the properties by choosing different elements for the cations. Doping either one or both of the cation sites opens up an even larger matrix for materials design.
