We present a detailed pressure study of the electrical resistivity ρ(T) and the specific heat C(T) of the non-Fermi-liquid (NFL) compound YbRh2Si2 and of ρ(T) for a single crystal in which 5 at.% of Si is replaced by isoelectronic Ge. The magnetic

We report the first observation of non-Fermi-liquid (NFL) effects in a clean Yb compound at ambient pressure and zero magnetic field. The electrical resistivity and the specific-heat coefficient of high-quality single crystals of YbRh(2)Si(2) present

The crystallographic and low-temperature properties of the equiatomic Yb-based compounds YbPtIn, YbRhSn (hexagonal ZrNiAl structure), and YbNiGa (orthorhombic $\ensuremath{\epsilon}$-TiNiSi structure) are studied by means of x-ray diffraction, magnet

We present resistivity measurements on V2O3 single crystals in the metallic phase at high pressure and low temperatures. From the T2-coefficient we derive the pressure-dependent effective mass m ∗ , which shows a steep increase on approaching the m

We present electrical resistivity ( ρ ) and AC magnetic susceptibility measurements on Ge-doped single crystals of the NFL compound YbRh 2 Si 2 . Upon producing the volume expansion (Δ V ≃+0.3%) necessary to tune this material to its QCP, the low

YbRh2Si2 is identified to be one of the few stoichiometric and the first Yb-based heavy fermion compound showing non-Fermi-liquid (NFL) effects at ambient pressure. We present results of a detailed study of the electrical resistivity ρ(T) and the sp

Strong deviations from the properties of a heavy Landau Fermi-liquid already at ambient pressure and zero field are reported for single-crystalline YbRh2Si2. The low-temperature specific-heat coefficient and the electrical resistivity show a logarith
