Interplay between unconventional superconductivity and heavy-fermion quantum criticality: CeCuSi versus YbRhSi
M. Smidman, O. Stockert, J. Arndt +25
In this paper the low-temperature properties of two isostructural canonical heavy-fermion compounds are contrasted with regards to the interplay between antiferromagnetic (AF) quan…
Evolution from Ferromagnetism to Antiferromagnetism in Yb(Rh1-xCox)2Si2
S. Hamann, J. Zhang, D. Jang +10
Yb(Rh1-xCox)2Si2 is a model system to address two challenging problems in the field of strongly correlated electron systems: The first is the intriguing competition between ferroma…
Emergence of superconductivity in the canonical heavy-electron metal YbRh2Si2
Erwin Schuberth, Marc Tippmann, Lucia Steinke +8
We report magnetic and calorimetric measurements down to T = 1 mK on the canonical heavy-electron metal YbRh2Si2. The data reveal the development of nuclear antiferromagnetic order…
Evidence for a Kondo destroying quantum critical point in YbRh2Si2
Frank Steglich, Heike Pfau, Stefan Lausberg +10
The heavy-fermion metal YbRhSi is a weak antiferromagnet below K. Application of a low magnetic field T () is sufficient to conti…
Thermal and Electrical Transport across a Magnetic Quantum Critical Point
H. Pfau, S. Hartmann, U. Stockert +11
A quantum critical point (QCP) arises at a continuous transition between competing phases at zero temperature. Collective excitations at magnetic QCPs give rise to metallic propert…
Avoided ferromagnetic quantum critical point: Unusual short-range ordered state in CeFePO
S. Lausberg, J. Spehling, A. Steppke +9
Cerium 4f electronic spin dynamics in single crystals of the heavy-fermion system CeFePO is studied by means of ac-susceptibility, specific heat and muon-spin relaxation (SR). S…
Type I Superconductivity in YbSb2 Single Crystals
Liang L. Zhao, Stefan Lausberg, H. Kim +4
We present evidence of type I superconductivity in YbSb2 single crystals, from DC and AC magnetization, heat capacity and resistivity measurements. The critical temperature and cri…
Huge First-Order Metamagnetic Transition in the Paramagnetic Heavy-Fermion System CeTiGe
Micha Deppe, Stefan Lausberg, Franziska Weickert +5
We report on the observation of large, step-like anomalies in the magnetization (\,/Ce), in the magnetostriction (), and in the…
Ferromagnetic Quantum Criticality in the Quasi-One-Dimensional Heavy Fermion Metal YbNi4P2
C Krellner, S Lausberg, A Steppke +7
We present a new Kondo-lattice system, YbNi4P2, which is a clean heavy-fermion metal with a severely reduced ferromagnetic ordering temperature at T_C=0.17K, evidenced by distinct…
