Kondo Destruction in Heavy Fermion Quantum Criticality and the Photoemission Spectrum of YbRhSi
S. Paschen, S. Friedemann, S. Wirth +3
Heavy fermion metals provide a prototype setting to study quantum criticality. Experimentally, quantum critical points have been identified and studied in a growing list of heavy f…
Interplay of structure, magnetism, and superconductivity in Se substituted iron telluride with excess Fe
Dona Cherian, S. Rößler, S. Wirth +1
We investigated the evolution of the temperature-composition phase diagram of FeTe upon Se substitution. In particular, the effect of Se substitution on the two-step, coupl…
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…
Pressure-induced phase transitions and high-pressure tetragonal phase of Fe1.08Te
C. Koz, S. Rößler, A. A. Tsirlin +6
We report the effects of hydrostatic pressure on the temperature-induced phase transitions in Fe1.08Te in the pressure range 0-3 GPa using synchrotron powder x-ray diffraction (XRD…
First-order structural transition in the magnetically ordered phase of Fe1.13Te
S. Rößler, Dona Cherian, W. Lorenz +8
Specific heat, resistivity, magnetic susceptibility, linear thermal expansion (LTE), and high-resolution synchrotron X-ray powder diffraction investigations of single crystals Fe1+…
