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,
.
