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.
