Query: Non-Fermi liquid regime in metallic pyrochlore iridates: Quantum
  Griffiths singularities   We investigate the interplay of Kondo and RKKY coupling in presence of
disorder by chemically substituting local moment Cr^{3+} at the Ir sublattice
in the metallic Pr_{2}Ir_{2}O_{7}. We find evidence of non-Fermi liquid (NFL)
behaviour in the transport and thermodynamic measurements at low temperature.
Specifically, the magnetic susceptibility exhibits power law divergence at T=0.
The nonanalytic temperature and magnetic-field dependence of magnetic
susceptibility and the associated scaling suggest existence of a two-fluid
system consisting of Kondo-screened paramagnetic metal coexisting with
magnetically ordered rare regions dominated by inter-impurity interaction,
similar to quantum critical Griffiths phase.
