Quantum phase transition in the heavy-fermion compound YbIrSi
H. Q. Yuan, M. Nicklas, Z. Hossain +2
We investigate the pressure-temperature phase diagram of YbIrSi by measuring the electrical resistivity . In contrast to the widely investigated YbRhSi, YbIr$…
Spin dynamics of observed by Electron Spin Resonance
J. Sichelschmidt, J. Wykhoff, H. -A. Krug von Nidda +3
Below the Kondo temperature electron spin resonance (ESR) usually is not observable from the Kondo-ion itself because the characteristic spin fluctuation energy results…
Observation of an optical non-Fermi-liquid behavior in the heavy fermion state of YbRhSi
S. Kimura, J. Sichelschmidt, J. Ferstl +3
We report far-infrared optical properties of YbRhSi for photon energies down to 2 meV and temperatures 0.4 -- 300 K. In the coherent heavy quasiparticle state, a linear…
Quantum criticality in the cubic heavy-fermion system CeIn_{3-x}Sn_x
R. Kuechler, P. Gegenwart, J. Custers +5
We report a comprehensive study of CeInSn single crystals close to the antiferromagnetic (AF) quantum critical point (QCP) at …
Multiple energy scales at a quantum critical point
P. Gegenwart, T. Westerkamp, C. Krellner +6
We report thermodynamic measurements in a magnetic-field-driven quantum critical point of a heavy fermion metal, YbRhSi. The data provide evidence for an energy scale in th…
Quantum Criticality in doped CePd_1-xRh_x Ferromagnet
J. G. Sereni, T. Westerkamp, R. Kuechler +3
CePd_1-xRh_x alloys exhibit a continuous evolution from ferromagnetism (T_C= 6.5 K) at x = 0 to a mixed valence (MV) state at x = 1. We have performed a detailed investigation on t…
