Abstract
The thermal conductivity of a single crystal of the spin ladder cuprate Sr 12Ca 2Cu 24O 41 has been measured in the temperature region between 5 and 300 K. An anomalous double-peak structure of the temperature dependence of the thermal conductivity parallel to the c-axis, i.e. along the ladder direction, is observed. The high-temperature peak is absent in the thermal conductivity parallel to the a-axis. We suggest that the high-temperature peak is caused by an unconventional mechanism of one-dimensional heat transport, which acts at temperatures exceeding approximately 40 K.
