RECONSTRUCTED FERMI SURFACE IN THE CHARGE-DENSITY-WAVE STATE OF TiSe2
Owen Moulding and Sven Friedemann, University of Bristol. TiSe2 features a charge density wave (CDW) driven by condensation of excitons, i.e., pairs of electrons and holes, alongside electronphonon coupling. [...]
ORIGIN OF THE LARGE UPPER CRITICAL FIELD OF A STOICHIOMETRIC IRON-BASED SUPERCONDUCTOR, CaKFe4As4
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 [...]
EVIDENCE FOR AN EXOTIC HIGH-FIELD SUPERCONDUCTING STATE IN FeSe
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 [...]
SCAFFOLD-FREE AND LABEL-FREE BIOFABRICATION TECHNOLOGY USING LEVITATIONAL ASSEMBLY IN HIGH MAGNETIC FIELD
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 [...]
FERMI-SURFACE INSTABILITIES IN THE HEAVY-FERMION SUPERCONDUCTOR UTe2
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 [...]
LOCALIZED VERSUS DELOCALIZED 5f ELECTRONS IN ANTIFERROMAGNETIC U2Rh2Sn
Denis Gorbunov, HLD Dresden. The physical properties of uranium-based intermetallic compounds depend strongly on the degree of localization of the 5f electrons. The extended character of the 5f states [...]
APERIODIC QUANTUM OSCILLATIONS IN THE TWO-DIMENSIONAL ELECTRON GAS AT THE LaAlO3/SrTiO3 INTERFACE
Walter Escoffier, Michel Goiran, LNCMI Toulouse and Km Rubi, HFML Nijmegen. The discovery of a two-dimensional electron gas (2DEG) at the interface between the two insulators LaAlO3 (LAO) and [...]
NMR STUDY OF CHARGE-DENSITY WAVES UNDER HYDROSTATIC PRESSURE IN YBa2Cu3Oy
Igor Vinograd and Marc-Henri Julien, LNCMI-Grenoble. High-temperature superconductivity in the cuprates arises in close proximity to a charge density wave (CDW) phase. A challenge in the field is to [...]
THREADING FLUX THROUGH HELIXES
Rosa Córdoba, ICMol and Uli Zeitler, HFML Nijmegen. The fabrication and understanding of complex three-dimensional (3D) architectures on the nanoscale is one of the promising routes towards new schemes [...]
MAGNETIC SHAPE MEMORY EFFECTS AND MAGNETO-STRUCTURAL COUPLING IN Fe1+yTe
S. Rößler, S. Wirth, MPI CPfS Dresden and Y. Skourski, HLD Dresden In recent years, the iron chalcogenides received considerable attention in the condensed-matter physics community which was mainly [...]
