Abstract

The dielectric response (100 Hz to 6 MHz), relaxation-time distribution, dielectric hysteresis loops and polarization obtained from pyroelectric current have been studied in the Cd₂Nb₂O₇ pyrochlore the ferroelectric (FE) state of which is frustrated due to embedded polar nanoregions of the nonergodic relaxor state (NERS). It is found that at frequencies below 1.5 MHz for dc bias electric fields of <7 kV/cm the contribution of a relaxor state dominates over that of a normal FE state. A proper formation of glassy or FE properties of the NERS is prearranged during zero-field cooling and field cooling the system through the freezing temperature T_f ≈ 182 K, respectively.
