We present experimental evidence for a dramatic suppression of
the phononic thermal conductivity of rare-earth– and
Sr–doped 
. Remarkably, this suppression correlates with
the occurrence of superconductivity. Conventional models for the phonon heat
transport fail to explain these results. In contrast,
a straightforward explanation is possible in terms of static and
dynamic stripe correlations of holes and spins.
