Thermal Conductivity of Some Ferroelectric Crystals with Hydrogen Bonds

The thermal conductivity of KH 2 PO 4 , KD 2 PO 4 and KH 2 AsO 4 single crystals was measured in the temperature range from 4.5 to 300°K. For all the samples critical changes of the thermal conductivity are found at the Curie temperatures. The conductivity decreases gradually with falling temperatur... View More
