Figure 7

Magnetoelectric coupling measurements.

(a) Magnetic force microscopy phase image after poling at −6 V (bright) and +6 V (dark). (b) and (c) Magnetic force microscopy phase image recorded biasing the tip with −2 V and +2 V, respectively. In (a–c) the figure size is 40 μm by 40 μm. (d) Temperature dependence of the magnetization (measured by SQUID) and its derivative (right-axis).
