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 [...]
PHASE-TRANSITION-INDUCED CARRIERMASS ENHANCEMENT IN 2D RUDDLESDEN− POPPER PEROVSKITES
Michal Baranowski and Paulina Plochocka, LNCMI-Toulouse Organic-inorganic halide perovskites have become the “next big thing” in emerging semiconductor materials, with their unprecedented rapid development and successful application in high-performance [...]
NEGATIVE THERMAL EXPANSION IN A MAGNETICALLY FRUSTRATED SPINEL
Lisa Rossi and Ben Bryant, HFML Nijmegen Frustrated magnets are materials with competing spin interactions, which cannot be simultaneously satisfied. While these materials have become most famous as a [...]
VISCOSITY MEASUREMENTS IN PULSED MAGNETIC FIELDS
Toshihiro Nomura* and Sergei Zherlitsyn, HLD Dresden. A quartz-crystal microbalance (QCM) is an ultrasensitive device to detect changes of the mass. When an external mass is coupled to the [...]
CYCLOTRON EMISSION FROM MASSLESS KANE ELECTRONS
Milan Orlita, LNCMI-Grenoble. When a magnetic field is applied to a solid, the continuous density of electronic states transforms into a set of discrete energy levels, known as Landau [...]
