Enhanced magneto-electric effect in manganite tricolor superlattice with artificially broken symmetry Project supported by the National Natural Science Foundation of China (Grant No. 61471301). |
(color online) Measurements of ME effect. (a) Schematic view of four electrodes fabricated on SL. (b) Polarization as a function of electric field (P–E) in SL film measured at T = 30 K under H = 0 kOe, 5 kOe, and 10 kOe. The frequency is 2 kHz. (c) Dependences of Ec and Pr on magnetic field. |
