Non-Fermi liquid regime in metallic pyrochlore iridates: Quantum Griffiths singularities

Bikash Ghosh, Vinod Kumar Dwivedi, Soumik Mukhopadhyay

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_{…
