The influene of an electric dc field E, on the temperature dependence of the dielectric coefficient E,, as well as on the temperature dependence of the elastic compliance coefficients sI1 and szz of Na&(SeO,), crystals is investigated. I t is shown that the intermediate phase (point group I) which exists in a small temperature range of about 0.8 K in the vicinity of 195 K is a pure ferroelastic phase and disappears a t dc field strengths E, 2 10 kV cm-'.Es wird der EinfIuB eines elektrischen Gleichfeldes E, sowohl auf die Temperaturabhangigkeit der Dielektrizitatskonstanten E,, als auch auf die Temperaturabhangigkeit der elastischen Nachgiebigkeiten sI1 und szz von NaH,(SeO,),-Kristallen untersucht. Dabei wird gezeigt, daO die in einem Bereich von etwa 0,s K in der Nahe von 195 K existierende Zwischenphase (Punktgruppe I) rein ferroelastisch ist und fur Gleichfeldstarken E, 2 10 kV cm-l verschwindet.

The influence of the concentration of deuterium on the temperature dependence of some elastic, dielectric and piezocoefficients is investigated. The replacement of hydrogen by deuterium and vice versa causes not only a large isotopic effect but also an important influence on the dielectric, elastic, and piezoelectric properties. A small concentration of hydrogen as well as deuterium is responsible for a “dip” in the temperature dependence of elastic, dielectric, and piezocoefficients and a middle concentration of both produces a diffusiness of the transition region.
