Evidence for a new magnetic field scale in CeCoIn5
I. Sheikin, H. Jin, R. Bel +6
The Nernst coefficient of CeCoIn5 displays a distinct anomaly at H_K ~ 23 T. This feature is reminiscent of what is observed at 7.8 T in CeRu2Si2, a well-established case of metama…
Thermal transport in the hidden-order state of URuSi
K. Behnia, R. Bel, Y. Kasahara +9
We present a study of thermal conductivity in the normal state of the heavy-fermion superconductor URuSi. Ordering at 18K leads to a steep increase in thermal conductiv…
Thermoelectricity of URuSi: giant Nernst effect in the hidden-order state
Romain Bel, Hao Jin, Kamran Behnia +2
We present a study of Nernst and Seebeck coefficients in the heavy-fermion compound URuSi, which hosts a phase transition of unsettled origin. A giant Nernst signal of…
Giant Nernst effect in a Kondo lattice close to a quantum critical point
R. Bel, K. Behnia, Y. Nakajima +5
We present a study of Nernst and Seebeck coefficients of the heavy-fermion superconductor CeCoIn. Below 18 K, concomitant with a field-dependent Seebeck coefficient, a large…
Ambipolar Nernst effect in NbSe
Romain Bel, Kamran Behnia, Helmut Berger
The first study of Nernst effect in NbSe reveals a large quasi-particle contribution with a magnitude comparable and a sign opposite to the vortex signal. Comparing the effect…
