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 the MD effect. (a) Dielectric constant and loss as functions of frequency for (3, 15) SL under external magnetic fields of 0 kOe, 5 kOe, and 10 kOe at T = 30 K. (b) Dielectric constant and loss as functions of temperature at different magnetic fields. (c) Temperature dependence of the MD effect. A maximum appears at 30 K. |
