We report heteroepitaxial growth of multiferroic BiFeO3 thin films by RF magnetron sputtering on lattice-matched SrTiO3 substrates, as well as preparation and electrical properties of the heterostructures formed by growing BiFeO3 thin films on highly conductive LaNiO3 films and n-Si substrates. Nonlinear and rectifying current-voltage (I-U) characteristics were revealed for the heterojunctions in a wide temperature range (T=78-300 K).
