Vincent Oliviero, David Vignolles, Cyril Proust, LNCMI Toulouse. In the last few years, high-magnetic-field studies have allowed great breakthroughs in the understanding of the physics of high-Tc cuprate superconductors. Here, we report the measurements of quantum oscillations and Hall effect in high magnetic fields up to 88 T in the [...]

Jan Wyzula, Milan Orlita, LNCMI-CNRS Grenoble and Mark O. Goerbig, LPS-CNRS Orsay Ever since the advent of graphene and topological materials, relativistic physics has become an integral part of condensed-matter sciences. While emergent, it is important to stress that this type of relativity is pertinent beyond the dispersion of the [...]

Peter Christianen, HFML Nijmegen. The development of pulsed, high-intensity terahertz free-electron lasers (FELs) has enabled the investigation of nonlinear phenomena in molecules and solids in the terahertz regime. To expand their potential, recently THz FELs were combined with high magnetic fields in some laboratories around the world. At HFML-FELIX, researchers [...]

Yurii Skourski, HLD Dresden. A group of researchers from Korea, USA, and HLD have demonstrated that topological nodal-line degeneracy of spin-polarized bands in magnetic semiconductors can induce an extremely large angular dependence in the magnetotransport. A phenomenon that the researcher called colossal angular magnetoresistance. The findings demonstrate that magnetic nodal-line [...]

Mateusz Dyksik, Wroclaw University of Science and Technology, Poland and Paulina Plochocka, LNCMI Toulouse. Optically inactive dark exciton states play an important role in light-emission processes in semiconductors because they provide an efficient nonradiative recombination channel. Understanding the exciton fine structure in materials with potential applications in light-emitting devices is, [...]

Jasper Linnartz and Steffen Wiedmann, HFML Nijmegen. A team of researchers from HFML-FELIX, Aarhus University, and the University of Bristol has investigated the high-field electronic transport properties of the semimetal WTe2. In quantum-oscillations measurements, they revealed peculiar magnetic-breakdown trajectories of charge carriers between nested pockets of the Fermi surface. WTe2 [...]

Ipsita Das, Dmitri K. Efetov, ICFO Spain and Benjamin A. Piot, LNCMI Grenoble. Different interacting phases such as correlated insulators, superconductors, magnetic states, Chern insulators, strange metals, anomalous quantum Hall effect etc. have been extensively studied in the flat band of magic-angle twisted bilayer graphene (MATBG) in the last few [...]

Frank Stefani und Thomas Herrmannsdörfer, HZDR and HLD Dresden. The heating of the Sun‘s corona to temperatures of several million kelvin is one of the major unsolved problems of solar physics. Although magnetic fields are unambiguously considered responsible for the “pot being hotter than the stove”, it remains controversial whether [...]

Michal Vališka, CEA-Grenoble and Charles University Prague, William Knafo, LNCMI Toulouse and Daniel Braithwaite, CEA-Grenoble. The discovery of superconductivity in the heavy-fermion paramagnet UTe2 has attracted a lot of attention, particularly due to the reinforcement of superconductivity near quantum phase transitions induced by magnetic field and/or pressure. In this system, [...]

Km Rubi and Uli Zeitler, HFML Nijmegen and Walter Escoffier, LNCMI Toulouse. A team of researchers from HFML-Nijmegen, LNCMI-Toulouse, and the National University of Singapore investigated the electronic properties of the quasi two-dimensional electron gas (2DEG) at a new 5d-oxide heterointerface, LaAlO3/KTaO3. The team induced high-mobility carriers at the interface [...]
