Interplay between field quantisation and Bloch states in graphene superlattices
Sergio Pezzini & Uli Zeitler, HFML Nijmegen Using high magnetic-magnetic fields, the Bloch states in two-dimensional graphene superlattices can be influenced in a way that adding fractions of flux [...]
NEW EUROPEAN RECORD FOR NONDESTRUCTIVE PULSED MAGNETIC FIELDS
Jérôme Béard, LNCMI-Toulouse On February 10, 2017, the LNCMI team in Toulouse has managed to generate, non-destructively, 98.8 T as shown in Figure 1. To obtain this [...]
A BREAKTHROUGH FOR EXTREME CONDITIONS: COMBINED HIGH PRESSURE AND PULSED MAGNETIC FIELD
William Knafo, LNCMI-Toulouse, Daniel Braithwaite, CEA-Grenoble, Rikio Settai, University of Niigata Combined extreme conditions of high pressure and strong magnetic field are an extremely powerful tool to [...]
PULSED HIGH MAGNETIC FIELD MEASUREMENT VIA A RUBIDIUM VAPOR SENSOR
Sylvie George, Nicolas Bruyant, Jérôme Béard, Stefano Scotto, Ennio Arimondo, Remy Battesti, Donatella Ciampini, Carlo Rizzo We have realized a new technique to measure pulsed magnetic fields [...]
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 [...]
