Abstract
The dimethyl-ammonium aluminum sulphate hexahydride (DMAAS) crystals h ave been studied by neutron diffraction in paraelectric and ferroelect ric phases. The coordinates and the thermal vibration ellipsoids of al l the atoms including hydrogen ones were determined. Disordering of DM A complex cation which plays an important role in ferroelectric phase transition was studied.
