Effects of microstructure on electric properties in BiFeO₃ – RMnO₃ thin films — •Claus-Henning Solterbeck, Abdelilah Lahmar, Salah Habouti, and Mohammed Es-Souni — Institute for Materials and Surface Technology, University of Applied Sciences Kiel, Germany

The interplay between structural and electric properties of BiFeO₃ (BFO) is not completely understood. For this comparative study, BFO thin films were grown by a sol-gel spin-coating method with incorporation of rare earth manganites (RMnO₃). The structure-property correlation is traced by several microscopic methods, but mainly with conductive-tip atomic force microscopy. For our non-epitaxial films, we investigate the effects of co-doping with RE-manganites on the local electric behaviour of the thin films, and we discuss it with respect to pure BFO.
