ELECTRONS IN FLAT BANDS
Layered materials can realize different stackings of their individual planes, different polytypes, to compose three-dimensional structures. ABA-stacked graphite is the most stable form of graphite at ambient [...]
Wide-Band Near-Infrared Spectroscopy Above 100 Tesla
O. Drachenko, A. Miyata, O. Portugall, P. Plochocka, A. Surrente, LNCMI-Toulouse and R. J. Nicholas, University of Oxford The Toulouse MegaGauss installation routinely generates magnetic fields well above 100 [...]
Magnetic-field suppression of thermoelectricity in a metallic frustrated magnet
Stevan Arsenijevič, HLD-HZDR Dresden and Nigel E. Hussey, HFML Nijmegen The thermoelectric effect (TE) in metals occurs as a voltage difference – accumulated charge – when a [...]
Nuclear Magnetic Resonance Signature of the Spin-Nematic Phase in LiCuVO4 at High Magnetic Fields
We report a 51V nuclear magnetic resonance investigation of the frustrated spin-1/2 chain compound LiCuVO4, performed in pulsed magnetic fields and focused on high-field phases up to 56 [...]
Broadband spectroscopy at extreme magnetic fields: First results
Alessandro Surrente, Atsuhiko Miyata, Oliver Portugall, and Paulina Plochocka, LNCMI-Toulouse Magnetic fields exceeding 100 T can be obtained only by semi-destructive methods. In one approach, the magnetic field [...]
Non-collinear Heusler antiferromagnet Pt2MnGa
Antiferromagnets (AFMs) have attracted increasing attention in state-of-the-art research. Their important role in enhancing the hardness of ferromagnetic electrodes through the exchange-bias effect in microelectronics, has been broadly extended [...]
Magneto-optics of monolayer tungsten disulfide
Peter Christianen, HFML Nijmegen Single-layer transition-metal dichalcogenides, such as MoS2, MoSe2, WS2, WSe2, are two-dimensional semiconductors with a honeycomb lattice. Their band structures show a pair of inequivalent [...]
