FIG. 1.

(Color online) (a) Intensity near the BiFeO3 (002) Bragg reflection as a function of time and wavevector qz during an electric field pulse with magnitude 102 MV/m and duration 12 ns. (b) Maps of diffracted intensity as a function of qz and in-plane wavevector qx near the BiFeO3 (002) Bragg reflection at zero field (left) and 217 MV/m (right). The SrRuO3 (002) reflection at q z = 3.173 Å−1 is cut off at high qz and low qx as a result of the angular range of the measurement.

FIG. 2.

(Color online) (a) Intensity vs. wavevector qz for the (002) BiFeO3 Bragg reflection at zero field (circles) and 178 MV/m (squares). (b) Piezoelectric strain as a function of electric field. The solid and dashed lines are linear fits for electric fields less than 150 MV/m and greater than 150 MV/m, respectively.

Image of FIG. 3.
FIG. 3.

(Color online) (a) Intensity as a function of the in-plane wavevector Δqxy for the BiFeO3 (002) Bragg reflection at zero field (circles) and 230 MV/m (squares). Here, Δqxy is the projection of the scattering wavevector onto the pseudocubic [110] direction (inset). (b) The peak intensity of BiFeO3 (002) Bragg reflection normalized to its zero-field value (upper panel), and the ratio of the diffuse and Bragg components of the scattering integrated over the ranges specified in the text (lower panel). The error bars are derived from counting statistics in the intensity integration.
