Composite (formula presented) films were prepared by metalorganic aerosol deposition on a (100)MgO substrate for different concentrations of the (MgO) phase (formula presented) At (formula presented) a percolation threshold in conductivity is reached, at which an infinite insulating MgO cluster forms around the (formula presented) grains. This yields a drastic increase of the electrical resistance for films with (formula presented) The film structure is characterized by x-ray diffraction and transmission electron microscopy. The local structure of the (formula presented) within the film depends on the MgO concentration which grows epitaxially along the domain boundaries. A different structural phase transition from the orthorhombic Pnma structure to an unusual rhombohedral (formula presented) structure at the percolation threshold (formula presented) is found for (formula presented) A three-dimensional stress accommodation in thick films through a phase transition is suggested. |
