Abstract

The thermal conductivity κ of a single crystal of superconducting

{Bi}_{2}

{Sr}_{2}

{CaCu}_{2}

O_{8}

has been measured at temperatures from 0.03 to 9 K. Below 2 K, where κ displays a

T^{2}

dependence, the results agree in both temperature dependence and magnitude with that of single-crystal superconducting

{YBa}_{2}

{Cu}_{3}

O_{7 - x}

or

{HoBa}_{2}

{Cu}_{3}

O_{7 - x}

, and are remarkably similar to the thermal conductivity of glasses.
