英文摘要	The electric-field-tunable non-volatile resistivity and ferromagnetism switching in the (La0.5Pr0.5)(0.67)Ca0.33MnO3 films grown on (111)-oriented 0.7Pb(Mg1/3Nb2/3)O-3-0.3PbTiO(3) ferroelectric single-crystal substrates have been investigated. By combining the 180 degrees ferroelectric domain switching and in situ X-ray diffraction and resistivity measurements, we identify that this voltage control of order parameters stems from the domain switching-induced accumulation/depletion of charge carriers at the interface rather than induced lattice strain effect. In particular, the polarization-induced charge effect (i.e., ferroelectric field effect) is strongly dependent on the magnetic field. This, together with the charge-modulated magnetoresistance and magnetization, reveals the strong correlation between the electric charge and the magnetic field. Further, we found that this coupling is essentially driven by the electronic phase separation, the relative strength of which could be determined by recording charge-tunability of resistivity [(Delta rho/rho)(charge)] under various magnetic fields. These findings present a potential strategy for elucidating essential physics of perovskite manganites and delivering prototype electronic devices for non-volatile information storage.
