Abstract
Investigations of improper ferroelectric phase transition in the crystals Rb(H,D)3(SeO3)2 are reviewed. It is shown that the peculiarities of elastic properties in the nonpolar phase of the crystals are not described by Landau theory. The elastic anomalies are proposed to be caused by the presence of the incommensurate structure predicted in these crystals theoretically.Keywords
