The competition between Kondo correlations and magnetic ordering in heavy fermion materials leads to emergent physics that is not fully understood. Seiro et al. show inter-site Kondo correlations only dominate over local ones at temperatures well below the single-ion Kondo temperature but this is a prerequisite for quantum critical behavior.
