Abstract:
The peculiarities of transport characteristics of non-equilibrium thermal phonons in ferroelectrics with diffuse phase transition (relaxors) have been analyzed at Helium temperatures. It was stated that appearance of «Plateau» region on temperature dependence of thermal conductivity in such materials may be caused by the «Gap» in phonon state spectrum.
