Abstract: We have examined the effects of converse piezoelectric effect induced lattice strains on the resistance of the La0.7Sr 0.3MnO3 (LSMO) thin films grown on (001)-oriented (1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3 (x∼0.3) (PMN-PT) single-crystal substrates. It has been found that the resistance of the LSMO films can be modulated by the converse piezoelectric effect of the PMN-PT substrates. Piezoelectric displacement measurements indicate that the converse piezoelectric effect induces lattice displacements in the PMN-PT substrates, which modulates the lattice strain and resistance of the LSMO films. Based on the experimental results, the relationship between the resistance of the LSMO films and the converse piezoelectric effect induced lattice strains in the PMN-PT substrates has been discussed.
