Mottled electronic state near a quantum critical phase transition

Description
By means of nuclear magnetic resonance (NMR) spin-lattice relaxation time measurements on a single crystal YbRh2Si2 sample, it is revealed that the coexisting Fermi and non-Fermi states appears near the quantum critical phase transition. Such a mottled state has remained hidden in Ce and U heavy fermion compounds, owing presumably to short lifetimes for the two states. Valence and magnetic instabilities are considered to occur at the same time around the quantum critical phase transition. (author)
