Abstract: The authors have deposited thin films of La[sub 0.85]Sr[sub 0.15]MnO₃ (LSMO) on 0.7Pb(Mg[sub ⅓]Nb[sub ⅔]O₃-0.3PbTiO₃(PMN-PT) single-crystal substrates and have achieved modulation of the resistance of the LSMO film by applying an electric field across the PMN-PT substrate whether the LSMO film is in the paramagnetic, ferromagnetic, or charge-ordered state. Piezoelectric measurements show that the electric field gives rise to a lattice strain in the PMN-PT substrate via the converse piezoelectric effect, which then induces a lattice strain and hence a resistance change in the LSMO film. Analysis of the data indicates that the electric-field-induced lattice strain effect dominates over the field effect in the LSMO/PMN-PT structure.
