AB - Enhanced electric field (E) induced modulation of the resistance of epitaxial thin films of Nd0.7Sr0.3MnO3has been observed. The results show several remarkable features: first, field-direction-independent decrease of the resistance above the temperature at which the peak in resistivity occurs (Tp); second, proportionality of the modulation to E2; third, a reduction in the magnitude and field-direction-independent reversal of the sign of ΔR/R just below Tp; and fourth, a prompt time response at high temperatures and a slower response near Tp. These results are consistent with a model of a polarization-induced lattice distortion coupling with both spin and charge transport. © 1996 The American Physical Society.
