The thermal conductivity at T < 0.5K parallel to the CuO2 planes in single crystalline YBa2Cu3O6.9 can be decomposed as κa,b(T) = κphonon(T) + A·T, while κc(T) = κphonon(T). This is explained by a model calculation, assuming that superconductivity is generated in the CuO2 layers and weak superconductivity is induced in the CUO chains by the proximity effect.
