The structural long-range B-site ordered domains and dielectric properties of the as-sintered and postannealed ceramics (0.4)Pb(In1/2Nb1/2)O3:(0.6)Pb(Mg1/3Nb2/3)O3 have been characterized. Transmission electron microscopy studies show an increase in the size of the ordered domains following annealing. In the low-field dielectric measurements, the longer the annealing time, the narrower is the diffuse phase transition. A high-temperature dielectric anomaly at low frequency in the as-sintered sample significantly weakens following postannealing. The annealed samples retained their exceptionally slim ferroelectric hysteresis loops. [ABSTRACT FROM AUTHOR] |
