Unified description of resistivity and thermopower of Pr${}_2$Ir${}_2$O${}_7$: possible influence of crystal field excitation in a Kondo lattice

Bikash Ghosh, Soumik Mukhopadhyay

We present experimental evidence of incoherent Kondo scattering as the source of resistivity minima in bulk polycrystalline and nanocrystalline Pr${}_2$Ir${}_2$O${}_7$. The temperature d…
