Pyroelectric, dielectric and thermal properties of LiRbS (SO4)3 1.5HzSO4 crystal in the temperature range from 100 to 400 K

Abstract Pyrbelectric, dielectric and thermal properties of LiRbS (SO4)3 -1. 5H2SO4 were studied in the temperature range from 100 to 400 K. At 137 K marked anomalous changes in pyroelectric and thermal properties were observed, Below 137 K ferroelastic domain structure was found to appear.
