摘要:

We demonstrate a photothermal method for making point measurements of the thermal conductivities of highTcsuperconductors. Images made at room temperature on polycrystalline materials show the thermal inhomogeneities. Measurements on single‐crystal Bi2Sr2CaCu2Oxcompounds reveal a very large anisotropy of about 7:1 in the thermal conductivity.
