N2 - A domain nucleation model of polarization dynamics in less understood anti-ferroelectric systems is introduced. Predictions of the model have been successfully tested experimentally using an anti-ferroelectric Pb0.99Nb0.02[(Zr0.57Sn0.43)0.94Ti0.06]0.98O3 polycrystalline ceramic. We determined the activation energy of the domain nucleation process for this particular anti-ferroelectric sample to be Wb = 1.07 eV and the critical volume of the polar nucleus V* = 98 10-27 m3, which corresponds to a linear length scale of 2.86 nm.
