Abstract:

In order to study the important of Casimir phonon scattering on the thermal conductivity of La1.8Sr0.2CuO4, we measure the thermal conductivity between 1 and 30 K on samples of different grain sizes. We conclude that it starts to be important in this temperature range for grain sizes d < 10 μm. The other phonon scattering mechanisms to understand the thermal conductivity temperature dependence are scattering against stacking faults or twin walls and tunnelling systems analogous to those found in glasses. © 1990.
