Evolution of the Kondo lattice and non-Fermi liquid excitations in a heavy-fermion metal
S. Seiro, L. Jiao, S. Kirchner +7
Strong electron correlations can give rise to extraordinary properties of metals with renormalized quasiparticles which are at the basis of Landau's Fermi liquid theory. Near a qua…
Experimental Determination of the Fermi Surface of Sr3Ir4Sn13
Xiaoye Chen, Swee K. Goh, David A. Tompsett +11
The stannide family of materials A3T4Sn13 (A = La,Sr,Ca, T = Ir,Rh) is interesting due to the interplay between a tunable lattice instability and phonon-mediated superconductivity…
Atomic Diffusion in the Surface State of Mott Insulator NiS2
C. Clark, S. Friedemann
We present resistivity measurements of Mott insulator NiS2 single crystals after heat treatment. We find a strong increase of the low temperature resistivity that relaxes back towa…
Lifshitz transitions and quasiparticle de-renormalization in YbRhSi
H. R. Naren, S. Friedemann, G. Zwicknagl +4
We study the effect of magnetic fields up to 15 T on the heavy fermion state of YbRhSi via Hall effect and magnetoresistance measurements down to 50 mK. Our data show anoma…
Interplay between Kondo suppression and Lifshitz transitions in YbRhSi at high magnetic fields
H. Pfau, R. Daou, S. Lausberg +11
We investigate the magnetic field dependent thermopower, thermal conductivity, resistivity and Hall effect in the heavy fermion metal YbRh2Si2. In contrast to reports on thermodyna…
Comment on "Zeeman-Driven Lifshitz Transition: A Model for the Experimentally Observed Fermi-Surface Reconstruction in YbRh2Si2"
S. Friedemann, S. Paschen, C. Geibel +5
In Phys. Rev. Lett. 106, 137002 (2011), A. Hackl and M. Vojta have proposed to explain the quantum critical behavior of YbRh2Si2 in terms of a Zeeman-induced Lifshitz transition of…
Electrical resistivity ofYb(Rh1-xCox)2Si2 single crystals at low temperatures
S. Friedemann, N. Oeschler, C. Krellner +2
We report low-temperature measurements of the electrical resistivity of Yb(Rh1-xCox)2Si2 single crystals with 0 <= x <= 0.12. The isoelectronic substitution of Co on the Rh site le…
