Anisotropy of the thermal conductivity in blue bronze

We have measured the thermal conductivity of K0.3MoO3 (blue bronze) in the chain direction and in both perpendicular directions from 80 to 300 K. As expected, it shows an anisotropic behaviour in lattice contribution as well as in free carrier contribution. These results are in favor to our previous explanation that there are residual anomalies in thermal conductivity resulting from the contribution of low-frequency phasons of rather large velocities.
