Thermal diffusivity of Bi2Sr2CaCu2O8 single crystals


Journal Article

We have made direct measurements of the temperature dependence of the thermal diffusivity along all three axes of a single- crystal Bi2Ca2SrCu2O8 superconductor. We find that the thermal diffusivity is enhanced dramatically along the Cu-O planes below Tc. From our results, we estimate a 40% electronic contribution to the diffusivity along the Cu-O planes. At room temperature the total anisotropy in thermal diffusivity is 7:1, while the lattice contribution has only a 4.2:1 anisotropy. © 1993.
