Temporal relaxation of the field-induced remanent polarization has been measured on at temperatures between 19.1 and . It is described in terms of Chamberlin's theory of dynamically correlated domains. Activated dynamics with correlation coefficients C>0 outside the freezing region, and , is traced back to activated cluster and domain wall dynamics, respectively. Non-activated dynamics within hints at late-stage wall relaxation of percolating polar clusters in the vicinity of the glass transition, .
