Abstract

Dielectric and optical investigations of (NH₄)₄LiH₃(SO₄)₄ and (NH₄)₄LiH₃(SeO₄)₄ single crystals showed that these crystals are new ferroelastic below 233 K and 267 K respectively. X-ray studies demonstrated that above mentioned crystals are isomorphous with other representatives of Me₄LiH₃(XO₄)₄ family and undergo transition from paraelastic tetragonal (P₄₁ or P₄₃) to ferroelastic monoclinic (P₂₁) phase.
