Abstract
Dielectric dispersion is shown to occur at microwave frequencies in single crystals of PbCo1/2W1/2O3 in the frequency range of 0.5-500 GHz. The freque ncy dependence of this dispersion can be explained in terms of a strongly d amped ferroelectric soft mode occurring in the incommensurate phase and nea r each of the paraelectric-incommensurate and incommensurate-ferroelectric transitions.
