YbRh 2 Si 2 : Pronounced Non-Fermi-Liquid Effects above a Low-Lying Magnetic Phase Transition
O. Trovarelli,C. Geibel,S. Mederle,C. Langhammer,F. M. Grosche,Philipp Gegenwart,Michael Lang,G. Sparn,Frank Steglich +8 more
TL;DR: In this article, the first observation of non-Fermi-liquid effects in a clean Yb compound at ambient pressure and zero magnetic field was reported, and the authors ascribe this NFL behavior to the presence of quasi-2D antiferromagnetic spin fluctuations related to a very weak magnetic phase transition at T(N) approximately 65 mK.
Journal ArticleDOI
Low-temperature properties of the Yb-based heavy-fermion antiferromagnets YbPtIn, YbRhSn, and YbNiGa
O. Trovarelli,C. Geibel,R. Cardoso,S. Mederle,R. Borth,B. Buschinger,F. M. Grosche,Yuri Grin,G. Sparn,Frank Steglich +9 more
TL;DR: In this article, the properties of equiatomic Yb-based compounds YbPtIn, YbRhSn, and YbNiGa were studied by means of x-ray diffraction, magnetic susceptibility, magnetization, electrical resistivity, magnetoresistance, thermoelectric power, and specific heat measurements.
Journal ArticleDOI
An unconventional metallic state in YbRh2(Si1-xGex)2: a high pressure study
TL;DR: In this article, 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 ρ (T) for a single crystal in which 5 at% of Si is replaced by isoelectronic GeThe magnetic phase diagram is deduced up to p ~ = 25 GPa.
Journal ArticleDOI
Magnetic, transport, and thermal properties of Yb2T3X9 compounds (T = Rh, Ir; X = Al, Ga)
O. Trovarelli,C. Geibel,B. Buschinger,R. Borth,S. Mederle,M. Grosche,G. Sparn,Frank Steglich,O. Brosch,L. Donnevert +9 more
TL;DR: In this paper, the low-temperature properties of a family of ytterbium-based compounds with the composition were studied by means of magnetic susceptibility, electrical resistivity, thermoelectric power, and specific-heat measurements.
Journal ArticleDOI
Non-Fermi-liquid effects at ambient pressure in the stoichiometric heavy-fermion compound YbRh2Si2
O. Trovarelli,C. Geibel,C. Langhammer,S. Mederle,Philipp Gegenwart,F. M. Grosche,Michael Lang,G. Sparn,Frank Steglich +8 more
TL;DR: In this paper, strong deviations from the properties of a heavy Landau Fermi-liquid already at ambient pressure and zero field are reported for single-crystalline YbRh2Si2.
