TiSe2 features a charge density wave (CDW) driven by condensation of excitons, i.e., pairs of electrons and holes, alongside electronphonon coupling. The CDW transition at 202 K gaps out most of the Fermi surface. Quantum-oscillation measurements at the HFML Nijmegen provide [...]

Matthew Bristow, Amalia Coldea, University of Oxford and William Knafo, LNCMI-Toulouse. CaKFe4As4 belongs to a new family of 1144 iron-based superconductors. It is a clean and stoichiometric superconductor with a relatively high critical temperature of 35 K. This system lacks long-range magnetic order or a nematic electronic state at [...]
S. Kasahara, Kyoto University, N. Hussey, HFML Nijmegen, and J. Wosnitza, HLD Dresden. Superconductivity is destroyed at high magnetic fields. Usually, the highest field up to which this state can exist is the Pauli paramagnetic limit, when the Zeeman energy of the itinerant electrons becomes larger than the superconducting [...]
Hans Engelkamp and Peter Christianen, HFML Nijmegen. This research shows that magnetic levitational bioassembly with a non-toxic, low concentration of a paramagnetic medium in high magnetic field is technologically feasible. Moreover, the experimental results confirm that it can be used as a cost-effective alternative to microgravity research at the [...]
Alexandre Pourret, CEA Grenoble and Gabriel Seyfarth, LNCMI-Grenoble. The recently discovered heavy-fermion superconductor UTe2 with superconducting transition temperature of 1.6 K is one of the rare examples of a heavy-fermion material with superconductivity appearing above 1 K. In contrast to the ferromagnetic heavy-fermion superconductors UCoGe and URhGe, UTe2 is [...]
Wuhan, capital city of Hubei province in the People‘s Republic of China, was the first urban center worldwide to get hit hard by the Corona pandemic. Now, months later, the situation on site is slowly getting back to normal. On April 8, 2020, the Wuhan lockdown officially ended. Meanwhile, [...]

He came from the Forschungszentrum Jülich, where he was a member of the Executive Board and has been responsible since November 2007 for the research [...]
Together with partners the three European Magnetic Field Laboratories, joined in EMFL, have been awarded two EU Horizon 2020 grants: one to develop all-superconducting user magnets beyond 40 Tesla (2.9 M€), and one to expand EMFL’s industrial and user community (4.9 M€). With these grants, EMFL will strengthen its [...]
