Comment on "Signatures of Surface States in Bismuth at High Magnetic Fields"
Kamran Behnia
Nernst effect is the transverse electric field due to a longitudinal thermal gradient in presence of magnetic field. Its magnitude was recently studied up to 33 T in a bismuth sing…
Nernst effect and dimensionality in the quantum limit
Zengwei Zhu, Huan Yang, Benoit Fauque +2
Nernst effect, the transverse voltage generated by a longitudinal thermal gradient in presence of magnetic field has recently emerged as a very sensitive, yet poorly understood, pr…
Anisotropic inelastic scattering and its interplay with superconductivity in URuSi
Zengwei Zhu, Elena Hassinger, Zhu'an Xu +3
In contrast to almost all anisotropic superconductors, the upper critical field of URuSi is larger when the field is oriented along the less conducting direction. We pr…
Polar phonons and spin excitations coupling in multiferroic BiFeO3 crystals
P. Rovillain, M. Cazayous, Y. Gallais +4
Raman scattering measurements on BiFeO3 single crystals show an important coupling between the magnetic order and lattice vibrations. The temperature evolution of phonons shows tha…
An electronic instability in bismuth far beyond the quantum limit
Benoit Fauque, Baptiste Vignolle, Cyril Proust +2
We present a transport study of semi-metallic bismuth in presence of a magnetic field applied along the trigonal axis extended to 55 T for electric conductivity and to 45 T for the…
Fermi surface instability at the hidden-order transition of URu2Si2
A. F. Santander-Syro, M. Klein, F. L. Boariu +3
Solids with strong electron correlations generally develop exotic phases of electron matter at low temperatures. Among such systems, the heavy-fermion semi-metal URu2Si2 presents a…
