Abstract: According to the method proposed by Swarts and Shrout, PMN ceramic material with single perovskite phase was prepared, and no any pyrochloride one was detected by X-ray diffraction analyses. SEM observation shows that the sample was dense without the apparent pores. The hysteresis (P ∼ E) loop was measured by using a Radiant Technology RT 66a and an amplifier. The change of P ∼ E loop of the sample with the frequency measured shows that the dependence of the polarization on the field of PMN relaxor ferroelectric ceramic material at low frequency (e.g. 10 Hz) is a curve without any hysteresis at room temperature, and P ∼ E loop appears with the increase of frequency measured(e.g.>100 Hz), the higher the frequency, the larger the P ∼ E loop, which differs from that of normal ferroelectrics.
