Domain freezing is observed for the first time in triglycine sulphate. A new domain freezing model is proposed based upon the collective-pinning of random distributing pinning centers to DW's, and Vogel-Fulcher relation, which describes the relaxation during the process of domain freezing successfully, is deduced.
