摘要：

We study the E-T phase diagram and dynamical pyroelectric coefficient of an (001)-oriented flux-grown 0.8Pb(Mg1/3Nb2/3)O-3-0.2PbTiO(3) single crystal. We found that the highest pyroelectric coefficient can be achieved at the point having quasicritical features. These data establish a quasicritical behavior of the field-induced pyroelectric coefficients in relaxors. (C) 2008 American Institute of Physics.
