Thermal and dielectric properties of KH₂PO₄ at very low temperatures

Abstract

Specific heat capacity, thermal conductivity and complex dielectric constant of KH₂ PO₄ have been measured to temperatures as low as 0.1 K. An increase of glasslike anomalies of the specific heat and the thermal conductivity after neutron irradiation has been found. After removing of an applied static electric field a logarithmic time dependence of the dielectric constant has been observed.
