| Popis: | The paper studies the effect of charge carrier doping on quantum criticality in the heavy-fermion metal YbRh2Si2. It focuses in particular on the critical temperature crossover-scale, which previously has been assigned as signature of the disintegration of heavy quasiparticles at the quantum critical point. The data are incompatible with the presumed Kondo breakdown and instead point at a Zeeman driven magnetic polarization underlying critical temperature. |
