Abstract

Pyrochlore iridates lie at a tuning-free magnetic quantum critical point hosting several complex exotic phenomena. Here, the authors discover an electronic phase separation in single crystalline Pr2Ir2O7, where well-defined Kondo resonances are interweaved with a non-magnetic metallic phase with Kondo-destruction.
