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 [...]
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 leads to a high sensitivity to external parameters. The pronounced spin-orbit interaction of uranium provides significant orbital polarization of the [...]
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 SrTiO3 (STO) has not only enhanced the expectations of oxide-electronics but has also brought new and exciting opportunities to explore [...]
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 understand how both phenomena compete and whether, behind pure competition, there is a more involved relationship between them. To tackle [...]
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 for a next generation of advanced electronic devices. This endeavor requires advanced new processing technologies, state-of-the-art structural and electronic characterization [...]
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 sparked by the discovery of superconductivity below Tc ≈ 8.5 K in bulk FeSe. The binary sister compound Fe1+yTe is [...]
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 photovoltaics. Yet, their inherent instabilities with respect to moisture remain a crucial challenge for these materials. This directed the interest [...]
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 playground for novel phases, such as quantum spin liquids, they also exhibit technologically relevant properties, such as multiferroicity and an [...]
