Аннотация: The heat capacity of NH4LiSO4, RbLiSO4, and Cs-x(NH4)(1 - x) LiSO4 crystals and its behavior over a broad temperature range including the phase transition regions were studied. The entropy changes corresponding to structural transformations in these crystals were found not to be characteristic of straightforward ordering of structural blocks. The results obtained are discussed in terms of phenomenological theory and model concepts. (C) 2005 Pleiades Publishing, Inc.
