Abstract

The nucleation kinetics of the formation of ordered ferroelectric phases from the glassy relaxor states of PbMg1/3Nb2/3O3 (PMN) and of solid solutions of PMN and PbTiO3 is investigated. A delay time, dependent on field and temperature, is found to precede a rather rapid establishment of macroscopic polarization. The qualitative form of the temperature dependence follows prior theory for the lag preceding homogeneous nucleation of a crystal from a glass. However, the increase of the lag time as the "melting" line is approached from below is stronger than expected.
