Popis: Heavy-fermion materials have unusual electronic behavior due to a dual localized-itinerant character of 4f electrons. Here, by studying divalent EuRh2Si2, the authors gain insight into the electronic states of the trivalent heavy fermion system YbRh2Si2 and show that it experimentally demonstrates Luttinger’s theorem.
