INSULATING STATES OF REPLICA DIRAC FERMIONS IN GRAPHENE SUPERLATTICES
Sergio Pezzini, Steffen Wiedmann, Uli Zeitler, HFML Nijmegen. Two-dimensional layers of graphene and hexagonal boron nitride (hBN) both have a honeycomb atomic structure, with a slight lattice mismatch of [...]
THE HIGH FIELD HTS INSERT NOUGAT REACHED A RECORD FIELD OF 32.5 T
Jung-bin Song, X. Chaud, F. Debray, LNCMI-Grenoble and P. Fazilleau, T. Lécrevisse, CEA Saclay. The High Temperature Superconductor (HTS) team at LNCMI has set a new world record by [...]
HIGH MAGNETIC FIELDS PROBE MULTIEXCITON STATES IN ORGANIC MATERIALS
Leah Weiss, Sam Bayliss, University of Cambridge and Paulina Plochochka, LNCMI-Toulouse. Intermolecular coupling plays a key role in charge transport and excited-state dynamics in organic systems. A key example [...]
7 T METAL-AS-INSULATION HIGH-Tc MOCK-UP INSERT IN 20 T
Xavier Chaud, LNCMI Grenoble. The development of high-temperature superconductor (HTS) inserts for all superconducting magnets for fields above 23 T is highly desirable. With practically zero power consumption this [...]
SUPERCONDUCTING COIL FOR HFML’S 45 T HYBRID MAGNET
In the beginning of March 2018, a major milestone in the development of the 45 T hybrid magnet at HFML in Nijmegen has been achieved with the completion of [...]
EXPERIMENTAL OBSERVATION OF BETHE STRINGS
Zhe Wang, HZDR Dresden and A. Loidl, University of Augsburg. In his seminal work entitled “Eigenwerte und Eigenfunktionen der linearen Atomkette” (eigenvalues and eigenfunctions of a linear chain of [...]
HIGH-FIELD CHARGE ORDER ACROSS THE PHASE DIAGRAM OF YBCO
F. Laliberté, M. Frachet, S. Benhabib, B. Borgnic, C. Proust, D. LeBoeuf, LNCMI-Toulouse. In hole-doped cuprates there is now compelling evidence that inside the pseudogap phase, a charge density [...]
GATE-TUNING ACROSS THE SUPERCONDUCTING DOME OF MONOLAYER WS2
J. Lu, Peking University and J. Ye, University of Groningen and I. Leermakers, N. Hussey, U. Zeitler, HFML-Nijmegen. Compared with three-dimensional superconductors, atomically thin superconductors are expected to be [...]
HOW CHARGE ORDER WEAKENS SUPERCONDUCTIVITY IN YBa2Cu3Oy
Marc-Henri Julien, LNCMI Grenoble. The upper critical field, Hc2, is a fundamental, and technologically important property that measures the ability of a superconductor to withstand magnetic fields. Recently, there [...]
A MULTICALORIC COOLING CYCLE THAT EXPLOITS THERMAL HYSTERESIS
T. Gottschall, HLD Dresden. The giant magnetocaloric effect, in which large thermal changes are induced in a material on the application of a magnetic field, can be used for [...]
