curves of Pt/PZT/LSMO (a), Pt//PZT/LSMO in which the layer is deposited at 30 (b), 80 (c), 150 (d), and 300°C (e) in 2.0 Pa oxygen pressure and Pt//LSMO in which the layer is deposited at 30°C in 2.0 Pa oxygen pressure (f). The arrows indicate the voltage sweeping directions. The inset in (b) shows the curves measured after the PZT layer is poled to opposite directions.
