Abstract
The combination of an Ising model with antiferromagnetic interaction a nd the neighbour-facilitated Fredrickson-Anderson model allows a descr iption of the polarization decay of polarized materials below the glas s temperature T-g. The relaxation time for the polarization scales wit h the relaxation time of the alpha-process of the glass transition, an d shows a typical curvature in the In tau versus T-1 plot.
