Journal ArticleDOI
Synthesis and Thermoelectric Characterization of Bi2Te3 Nanoparticles
TL;DR: In this paper, a new reduction route to bismuth nanoparticles is described, which are then applied as starting materials in the formation of rhombohedral Bi2Te3 nanoparticles.
Journal ArticleDOI
First-order superconducting phase transition in CeCoIn5.
Andrea Bianchi,Roman Movshovich,Niels Oeschler,Philipp Gegenwart,Frank Steglich,Joe D. Thompson,P. G. Pagliuso,J. L. Sarrao +7 more
TL;DR: The superconducting phase transition in heavy fermion CeCoIn5 becomes first order when the magnetic field H parallel [001] is greater than 4.7 T, and the transition temperature is below T0 approximately 0.31T(c).
Journal ArticleDOI
Divergence of the grüneisen ratio at quantum critical points in heavy fermion metals.
R. Küchler,Niels Oeschler,Philipp Gegenwart,Tomasz Cichorek,K. Neumaier,O. Tegus,C. Geibel,J. A. Mydosh,Frank Steglich,Lijun Zhu,Qimiao Si +10 more
TL;DR: Low-temperature volume thermal expansion, beta, and specific heat, C, measurements on high-quality single crystals of CeNi2Ge2 and YbRh2(Si0.95Ge0.05)(2) which are located very near to quantum critical points are presented.
Journal ArticleDOI
Detaching the antiferromagnetic quantum critical point from the Fermi-surface reconstruction in YbRh2Si2
Sven Friedemann,T. Westerkamp,Manuel Brando,Niels Oeschler,Steffen Wirth,Philipp Gegenwart,Philipp Gegenwart,Cornelius Krellner,C. Geibel,Frank Steglich +9 more
TL;DR: In this paper, the evolution of the quantum criticality in YbRh2Si2 under chemical pressure was studied and the signature of the Kondo breakdown within the magnetically ordered phase, whereas negative pressure induces their separation, leaving an intermediate spin-liquid-type ground state over an extended range.
Journal ArticleDOI
Fermi-surface collapse and dynamical scaling near a quantum-critical point
Sven Friedemann,Niels Oeschler,Steffen Wirth,Cornelius Krellner,Christoph Geibel,Frank Steglich,Silke Paschen,Stefan Kirchner,Qimiao Si +8 more
TL;DR: In this article, the authors report in-depth measurements of the Hall effect in the heavy-fermion metal YbRh2Si2, a prototypical system for quantum criticality.
