Epitaxial thin film heterostructures of high dielectric PbZr{sub 1-x}Ti{sub x}O{sub 3} (PZT) and La{sub 1-x}A{sub x}MnO{sub 3} (A-divalent alkaline earth metals such as Sr (LSMO) and Ca (LCMO)) were grown on SrTiO{sub 3} substrates and their structure, temperature dependence of electrical resistivity, and magnetization were investigated as a function of the thickness of the LSMO(LCMO) layer. The microstructures of the samples were analyzed by TEM. By applying an electric field across the PZT layer, we applied a ferrodistortive pressure on the manganite layer and studied the correlations between lattice distortion and electric transport and magnetic properties of the CMR materials.
