Effect of pressure and Ir substitution in YbRh2Si2
M. E. Macovei, M. Nicklas, C. Krellner +2
In this article we present a study of the electrical resistivity of Yb(Rh-xIrx)2Si2, x=0.06, under high pressure and in magnetic field. Ir substitution is expanding the unit cell a…
Magnetotransport in the CeIrIn system: The influence of antiferromagnetic fluctuations
Sunil Nair, M. Nicklas, J. L. Sarrao +3
We present an overview of magnetotransport measurements on the heavy-fermion superconductor CeIrIn. Sensitive measurements of the Hall effect and magnetoresistance (MR) are use…
Analysis of the normal state magnetotransport in CeIrIn
Sunil Nair, M. Nicklas, J. L. Sarrao +3
We present an analysis of the normal state magnetotransport in the heavy fermion superconductor CeIrIn. The Hall effect and the transverse magnetoresistance in this material…
Divergence of the Magnetic Grüneisen Ratio at the Field-Induced Quantum Critical Point in YbRhSi
Y. Tokiwa, T. Radu, P. Gegenwart +2
The heavy fermion compound YbRhSi is studied by low-temperature magnetization and specific-heat measurements at magnetic fields close to the quantum critical…
Vortex avalanches in the non-centrosymmetric superconductor Li2Pt3B
C. F. Miclea, A. C. Mota, M. Sigrist +5
We investigated the vortex dynamics in the non-centrosymmetric superconductor Li_2Pt_3B in the temperature range 0.1 K - 2.8 K. Two different logarithmic creep regimes in the decay…
The precursor state to superconductivity in CeIrIn: Unusual scaling of magnetotransport
Sunil Nair, M. Nicklas, F. Steglich +4
We present an analysis of the normal-state Hall effect and magnetoresistance in the heavy fermion superconductor CeIrIn. It is demonstrated that the modified Kohler's scaling…
