Electrical properties of single-crystal PCN: temperature dependences of the dielectric permittivity (a) real part and (b) imaginary part of a PCN single crystal at various frequencies. (c) Vogul–Fulcher fitting of the imaginary part of the dielectric permittivity. The squares are the experimental results and the red line is the fitted result. (d) P–E hysteresis loop of single-crystal PCN measured at room temperature with a frequency of 10 Hz.
