| 中文摘要 | The impact of the lattice strain on the charge/orbital ordering state was studied by using a heterostructure composed with electrondoped La0.9Hf0.1MnO3 (LHMO) and ferro- and piezoelectric 0.67Pb(Mg1/3Nb2/3)O-3-0.33PbTiO(3). The ferroelectric poling induces a significant reduction in the biaxial tensile strain in the LHMO film, leading to a decrease in the film resistance over the whole temperature range and an increase in the insulator to metal transition temperature T (IM). The resistance of LHMO film exhibits different responses to the external electric fields and lattice deformation, which is attributed to the coactions of converse piezoelectric effect and ferroelectric polarity effect. The modification of charge/orbital ordering phase by the electric fields and ferroelectric polarization suggests that the unstable states in the manganites are sensitive to strain effects. |
