THERMAL CONDUCTIVITY OF THE INTERMEDIATE STATE OF SUPERCONDUCTORS. PART II

We have calculated the coefficient of thermal conductivity of the lamellar and filamentary structure of the intermediate state, assuming heat transfer along the interfaces between the phases, for the case where the electronic mean free path is appreciably longer than the characteristic dimensions a of the normal regions. We assume an arbitrary dispersion law for the electrons. The coefficient of thermal conductivity of the lamellar structure is independent of the electronic mean free path Z, while that of the filamentary structure decreases with increasing l as ln(l/a)/Z.
