Abstract

In 0,945PMN-0,055PZT solid solution the ac dielectric permittivity is studied in the frequency domain 40Hz-1MHz. The dielectric spectrum is found extremely enlarging as temperature lowers and showing glassy-like behavior. The nonequilibrium character of the dielectric spectrum measured in ac experiment is proposed to be the reason of difference between the l st extracted from ac experiment and the field cooled one.
