ELECTRICAL RESISTIVITY ACROSS A NEMATIC QUANTUM CRITICAL POINT
Nigel Hussey, HFML Nijmegen. It is not only elemental or ordinary metals that superconduct. Today, scientists are also fascinated by strange metals that undergo phase transitions (e.g. to a [...]
BRAZILIAN PHD INTERNSHIPS AT HFML: SUCCESSFUL COLLABORATION
Steffen Wiedmann, HFML Nijmegen. In 2017 and 2018, two PhD students from Brazil came to Nijmegen to do a part of their post-graduate program at the EMFL facility in Nijmegen. [...]
PRESSURE TUNING OF EXCHANGE COUPLINGS IN A FRUSTRATED MAGNET
Sergei Zvyagin, HLD Dresden. Spin-1/2 triangular-lattice Heisenberg antiferromagnets represent one of the most important classes of frustrated quantum magnets, demonstrating a complex interplay between geometrical frustration, quantum fluctuations, and [...]
PULSED-FIELD NMR STUDY OF CeIn3 UP TO 56 T
Yo Tokunaga, JAEA Tokai, Nicolas Bruyant, LNCMI-Toulouse, and Ilya Sheikin, LNCMI-Grenoble. Heavy-fermion materials exhibit a diverse range of fascinating phenomena including quantum phase transition (QPTs), non-Fermiliquid behavior, and novel [...]
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 [...]
