The paper is devoted to the study of ferroelastoelectric domain structure and peculiarities of nano- and microcrystals growth on the surface of [(CH3)2CHNH3]4Cd3Cl10 (IPACC) crystals. The domains in the ferroelastoelectric phase lying below 294 K were visualized using an atomic force microscope. It was shown that the surface morphology of IPACC crystals kept for a long time (from one up to twelve months) in open air undergoes considerable changes in comparison with the freshly cleaved samples. Our samples are characterized by the growth of nanocrystals at the first stage and larger microcrystals at the next stages of the sample aging. Other types of elements observed on the surface were nano- or microrods. The model describing the peculiarities of the surface morphology and domain structure modification arising in the process of aging was proposed.
