Thermal conductivity of DI-BSCCO tapes with stacked or sandwiched structure

We have measured the temperature dependence of the thermal conductivity, κ(T), for DI-BSCCO tapes sandwiched by various kinds of alloy tapes and for a stacked bundle in which six DI-BSCCO tapes were soldered. For the sandwiched samples, the shape of κ(T) is qualitatively the same as that for the bare DI-BSCCO tape and the absolute value of κ(T) depends on the species and the thickness of the alloy tape. κ(T) for the stacked bundle nearly coincides to that for the bare DI-BSCCO. The κ(T) for the sandwiched and stacked samples can be reproduced by the κ(T) of each constitutional part.
