摘要: After the specimen of A-site defect perovskite single crystal was manufactured, dielectric properties were studied between temperature range 10 and 800 K. The anomaly appeared at 50 K 650 K, and, about thermal hysteresis constant shown. ac-conductivity bulk showed lowest activation energy 0.43 eV 560~690 Based on results, it is assumed that 50K due to antiparallel shift -ion rearrangement -ion, respectively.
