Abstract
Thermal conductivity, specific heat capacity and complex dielectric constant of PSN ceramic have been measured from 0.1 K up to 100 K. The thermal conductivity increases after poling of the sample but no influence of an applied electric field on the specific heat and the dielectric constant has been detected. Below 0.3 K a strong decreasing of the density of states has been observed.Keywords
