(a) Magnetoelectric hysteresis curve of the PZT/LSMO at 100 K.^[39] (b) Room temperature XANES results for the two polarization states of the PZT. The left top inset shows the difference in x-ray absorption for the two PZT polarization states. The right bottom inset is the variation of the x-ray light absorption as a function of the applied gate voltage at a fixed energy, E = 6549.7 eV.^[40]
