Query: Inhomogeneous ordering in weakly coupled Heisenberg $S=1/2$ chains with
  random bonds   Long range magnetic ordering in the quasi-one-dimensional random-bond
antiferromagnet BaCu$_2$(Si$_{1-x}$Ge$_{x}$)$_2$O$_7$ is studied in $\mu$SR
experiments as a function of disorder strength. Compared to the disorder-free
parent materials, the saturation ordered moment is found to be considerably
reduced. Moreover, even in weakly disordered species, the magnetically ordered
state is shown to be highly inhomogeneous. The results are interpreted in terms
of weakly coupled random spin chains, governed by the ``infinite randomness``
fixed point.
