Определены коэффициенты теплового расширения и построены их концентрационные зависимости при различных температурах. Установлено, что указанные величины с составом х изменяются линейно. По полученным значениям коэффициентов теплового расширения рассчитаны температуры Дебая и среднеквадратичные динамические смещения атомов. Показано, что с повышением температуры значения температур Дебая уменьшаются, а среднеквадратичные динамические смещения атомов увеличиваются.</p></abstract><trans-abstract xml:lang="en"><p>The thermal expansion of single crystals of solid solutions (MnIn2S4)1–х•(AgIn5S8)х was measured by the dilatometric method in the temperature range 80–450 K. The coefficients of thermal expansion are determined and their concentration dependences at different temperatures are constructed. It is established that the indicated quantities with composition x vary linearly. From the obtained values of the coefficients of thermal expansion, the Debye temperatures and the mean-square dynamic displacements of the atoms are calculated. It is shown that as the temperature is raised, the Debye temperature decreases, and the mean square dynamic displacements of the atoms increase.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>монокристаллы</kwd><kwd>кристаллическая структура</kwd><kwd>параметр элементарной ячейки</kwd><kwd>коэффициент теплового расширения</kwd><kwd>температура Дебая</kwd></kwd-group><kwd-group xml:lang="en"><kwd>single crystals</kwd><kwd>crystal structure</kwd><kwd>unit cell parameter</kwd><kwd>thermal expansion coefficient</kwd><kwd>Debye temperature</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Метфессель З., Маттис Д.
