| Title: | Determination of the strain dependence of resistance in La[sub 0.7]Sr[sub 0.3]MnO₃/PMN-PT using the converse piezoelectric effect | Authors: | Zheng, RK Wang, Y Chan, HLW Choy, CL Luo, H |
Issue Date: | 5-Jun-2007 | Source: | Physical review. B, Condensed matter and materials physics, 5 June 2007, v. 75, 212102, p. 1-4 | Abstract: | We have deposited La[sub 0.7]Sr[sub 0.3]MnO₃ (LSMO) thin films on piezoelectric (1−x)Pb(Mg[sub ⅓]Nb[sub ⅔])O₃−xPbTiO₃ (x~0.3)(PMN-PT) single-crystal substrates and studied the effects of substrate-induced lattice strain on the resistance of the LSMO films. By applying electric fields across the PMN-PT substrate, we in situ induce an in-plane compressive (tensile) strain in the PMN-PT substrate via the converse piezoelectric effect. The induced strain is transferred to the LSMO film, which then imposes an in-plane compressive (tensile) strain on the LSMO film, thereby causing a linear decrease (increase) in the resistance of the LSMO film. Based on the experimental results, we establish quantitative relationships between the resistance of the LSMO film and the converse piezoelectric-effect-induced out-of-plane and in-plane strains in the PMN-PT substrate and LSMO film, respectively. | Keywords: | Lanthanum compounds Strontium compounds Lead compounds Electrical resistivity Piezoelectric materials Piezoelectric thin films |
