AbstractThin films of Pr 0.7Sr 0.3MnO 3 grown on 0.7PbMg 1/3Nb 2/3O 3-0.3PbTiO 3 substrates were reversibly strained via the converse piezoelectric effect. The transport properties of Pr 0.7Sr 0.3MnO 3 were effectively modulated by the electric fields across the substrate. The roles of strain were explored by measuring resistance as a function of electric field and temperature. For all samples, deviations from a linear resistance-voltage relation were found. Two quantities, area difference and standard deviation, were used to characterize the nonlinearity. Both the nonlinearity and magnitude of resistance modulation peak at temperatures close to those of metal-insulator transition, indicating that the competing phases significantly changes the behaviors of strain responses. © 2012 American Institute of Physics.
