摘要：

DMAAS (dimethylammonium aluminium sulfate hexahydrate) and DMAGaS (dimethylammonium galium sulfate hexahydrate) were grown and their dielectric permittivity and spontaneous polarization were measured. On the ground of these measurements one can propose nearly critical phase transition at 153.K for DMAAS crystal and two first-order phase transitions at 136 K and 116 K for DMAGaS. Additionally, these measurements confirmed the order-disorder character of phase transitions in both crystals of this family.
