Figure 2. Magnetic field control of electric polarization.

Figure 2

(a) The magnetodielectric ratio Δε(H)/ε(50 kOe) = [ε(H)-ε(5 kOe)]/ε(5 kOe) at selected temperatures. (b) The details of the magnetodielectric behavior around zero field. (c) The magnetoelectric phase diagram of BaSrCoZnFe11AlO22. (d) Magnetic field reversal of in-plane electric polarization at 100, 150, and 200 K. The inset shows the magnetoelectric current near zero magnetic field.
