Abstract
Thermal conductivity data of Pb (Mg1/3 Nb2/3) O3 (PMN) ceramics in the unpoled and poled state are presented. The measurements were performe d in the temperature range from 2 K up to 100 K. The thermal conductiv ity exhibits glass like behaviour. The data from 2 K to 15 K can be ex plained in terms of the soft potential model. The thermal conductivity of the poled sample is enhanced in comparision to the unpoled one.
