Field-Induced Lifshitz Transition without Metamagnetism in CeIrIn
D. Aoki, G. Seyfarth, A. Pourret +5
We report high magnetic field measurements of magnetic torque, thermoelectric power (TEP), magnetization, and de Haas-van Alphen (dHvA) effect in CeIrIn across 28 T, where a me…
Strong interband Faraday rotation in 3D topological insulator Bi2Se3
L. Ohnoutek, M. Hakl, M. Veis +11
The Faraday effect is a representative magneto-optical phenomenon, resulting from the transfer of angular momentum between interacting light and matter in which time-reversal symme…
Tuning valley polarization in a WSe2 monolayer with a tiny magnetic field
T. Smoleński, M. Goryca, M. Koperski +5
In monolayers of semiconducting transition metal dichalcogenides, the light helicity ( or ) is locked to the valley degree of freedom, leading to the possibility of optic…
Granular superconductivity and magnetic-field-driven recovery of macroscopic coherence in a cuprate/manganite multilayer
B. P. P. Mallett, J. Khmaladze, P. Marsik +6
We show that in PrLaCaMnO/YBaCuO (PLCMO/YBCO) multilayers the low temperature state of YBCO is very resistive and rese…
Critical Doping for the Onset of Fermi-Surface Reconstruction by Charge-Density-Wave Order in the Cuprate Superconductor LaSrCuO

The Seebeck coefficient of the cuprate superconductor LaSrCuO (LSCO) was measured in magnetic fields large enough to access the normal state at low temp…
Change of carrier density at the pseudogap critical point of a cuprate superconductor
S. Badoux, W. Tabis, F. Laliberté +10
The pseudogap is a central puzzle of cuprate superconductors. Its connection to the Mott insulator at low doping remains ambiguous and its relation to the charge order that rec…
Determination of the exciton binding energy and effective masses for the methylammonium and formamidinium lead tri-halide perovskite family
Krzysztof Galkowski, Anatolie Mitioglu, Atsuhiko Miyata +8
The family of organic-inorganic halide perovskite materials has generated tremendous interest in the field of photovoltaics due to their high power conversion efficiencies. There h…
Raman scattering in few-layer MoTe
M. Grzeszczyk, K. Gołasa, M. Zinkiewicz +5
We report on room-temperature Raman scattering measurements in few-layer crystals of exfoliated molybdenum ditelluride (MoTe) performed with the use of 632.8 nm (1.96 eV) las…
Do magnetic fields enhance turbulence at low magnetic Reynolds number ?
Alban Pothérat, Rico Klein
Imposing a magnetic field on a turbulent flow of electrically conducting fluid incurs the Joule effect. A current paradigm is that the corresponding dissipation increases with the…
Disorder-induced stabilization of the quantum Hall ferromagnet
B. A. Piot, W. Desrat, D. K. Maude +3
We report on an absolute measurement of the electronic spin polarization of the integer quantum Hall state. The spin polarization is extracted in the vicinity of (inclu…
