Influence of cellular substructure on the thermal conductivity of heterovalent solid solutions of fluorides

The thermal conductivity of single-crystal samples of Sr 0.88 La 0.09 Nd 0.03 F 2.03 and Sr 0.80 La 0.15 Nd 0.05 F 2.20 solid solutions, both with a cellular substructure and without it, have been investigated by the method of stationary longitudinal heat flow in the temperature range of 50–300 K.

Description
Summary:The thermal conductivity of single-crystal samples of Sr 0.88 La 0.09 Nd 0.03 F 2.03 and Sr 0.80 La 0.15 Nd 0.05 F 2.20 solid solutions, both with a cellular substructure and without it, have been investigated by the method of stationary longitudinal heat flow in the temperature range of 50–300 K. An anisotropy of thermal conductivity (related to the substructure) is established for a Sr 0.995 Nd 0.005 F 2.005 single crystal.
