Origin of the 30 T transition in CeRhIn in tilted magnetic fields
S. Mishra, D. Gorbunov, D. J. Campbell +9
We present a comprehensive ultrasound study of the prototypical heavy-fermion material CeRhIn, examining the origin of the enigmatic 30 T transition. For a field applied at 2$^…
Robust Fermi-Surface Morphology of CeRhIn across the Putative Field-Induced Quantum Critical Point
S. Mishra, J. Hornung, M. Raba +7
We report a comprehensive de Haas--van Alphen (dHvA) study of the heavy-fermion material CeRhIn in magnetic fields up to 70~T. Several dHvA frequencies gradually emerge at high…
Fermi surface reconstruction and dimensional topology change in Nd-doped CeCoIn
J. Klotz, K. Götze, I. Sheikin +8
We performed low-temperature de Haas-van Alphen (dHvA) effect measurements on a CeNdCoIn series, for x = 0.02, 0.05, 0.1, and 1, down to T = 40 mK using torque magn…
Quasi-two-dimensional Fermi surfaces with localized electrons in the layered heavy-fermion compound CePtIn
K. Götze, Y. Krupko, J. A. N. Bruin +8
We report measurements of the de Haas-van Alphen effect in the layered heavy-fermion compound CePtIn in high magnetic fields up to 35 T. Above an angle-dependent threshold…
Extremely high conductivity observed in the triple point topological metal MoP
Nitesh Kumar, Yan Sun, Michael Nicklas +20
Weyl and Dirac fermions have created much attention in condensed matter physics and materials science. Recently, several additional distinct types of fermions have been predicted.…
Magnetic field induced strong valley polarization in the three dimensional topological semimetal LaBi
Nitesh Kumar, Chandra Shekhar, J. Klotz +2
LaBi is a three-dimensional rocksalt-type material with a surprisingly quasi-two-dimensional electronic structure. It exhibits excellent electronic properties such as the existence…
Magnetotransport and de Haas-van Alphen measurements in the type-II Weyl semimetal TaIrTe
Seunghyun Khim, Klaus Koepernik, Dmitry V. Efremov +8
The layered ternary compound TaIrTe has been predicted to be a type-II Weyl semimetal with only four Weyl points just above the Fermi energy. Performing magnetotransport measur…
Quantum oscillations and the Fermi-surface topology of the Weyl semimetal NbP
J. Klotz, Shu-Chun Wu, Chandra Shekhar +8
The Weyl semimetal NbP was found to exhibit topological Fermi arcs and exotic magneto-transport properties. Here, we report on magnetic quantum-oscillation measurements on NbP and…
Quasi-two-dimensional Fermi surfaces of the heavy-fermion superconductor CePdIn
K. Götze, J. Klotz, D. Gnida +7
We report low-temperature de Haas-van Alphen (dHvA) effect measurements in magnetic fields up to 35 T of the heavy-fermion superconductor CePdIn. The comparison of the expe…
