The discovery that superconductivity can also be induced by direct interactions between electrons, for example mediated by their magnetic properties, was a real breakthrough. However, [...]

Sandra Kleuskens, HFML Nijmegen and IMM Radboud, Daniela Wilson, IMM Radboud, and Hans Engelkamp, HFML Nijmegen. Researchers of HFML-FELIX and the Radboud University have determined the magnetic anisotropy of polystyrene in poly-ethyleneglycol polystyrene polymersomes by magnetic birefringence and transmission electron microscopy. The magnetic anisotropy found is only a small fraction [...]

Tommy Kotte, HLD. The conventional classification of magnetic materials has long been based on their distinction as either ferromagnetic or antiferromagnetic, determined by the presence or absence of a discernible net magnetic moment. In the ferromagnetic state, the break of timereversal symmetry, coupled with spontaneous spin polarization in the electronic [...]

Simon Tardieu, Florence Lecouturier-Dupouy, LNCMI Toulouse, and Christophe Laurent, Université de Toulouse. The generation of record pulsed magnetic fields above 100 T requires the use of coils wound with low-resistivity wires in order to limit the heating, and with a very high mechanical strength in order to be able to [...]

D. Santos-Cottin, University of Fribourg, Milan Orlita, LNCMI-Grenoble and Ana Akrap, University of Fribourg. Weyl semimetals are an exciting new group of materials, showing unique signatures in their transport and optical behavior, inherited from their distinct topological features. The presence of nodes in the electronic band structure of Weyl semimetals [...]

P. Chudzinski, M. Berben, Queen’s University Belfast, UK, and N. E. Hussey, HFML-FELIX. A team of researchers from HFML-FELIX, UK, USA, and China have discovered a rare phenomenon known as “emergent symmetry” in Li0,9Mo6O17(LMO). At room temperature, LMO is a 1D metal (Tomonaga-Luttinger liquid or TLL). As it cools down, [...]

Catalina Salazar Mejia, HLD. Magnetic-refrigeration and hydrogen-liquefaction technology based on the magnetocaloric effect are emerging as climate-friendly alternatives to conventional methods. To make these applications a reality, the proper characterization of the respective materials is now more crucial than ever. It is necessary to determine the magnetocaloric and other physical [...]

Walter Escoffier, Michel Goiran, Mathieu Pierre, LNCMI Toulouse, and Oleg Makarovsky, University of Nottingham, UK. Perovskite/graphene field effect transistors (FETs) have garnered substantial attention owing to their unique optical properties and potential for applications in electronics and optoelectronics, including ultra-sensitive photon detectors and FETs for metrology. The charge-transfer processes at [...]

Michał Grzybowski, Eindhoven University of Technology and University of Warsaw, and Uli Zeitler, HFML Nijmegen. Antiferromagnetic thin-film materials are robust against a magnetic field making them promising to be used in numerous spintronic applications. The magnetic properties of an antiferromagnet are governed by the competition between the magneto-crystalline anisotropy and [...]

Artem Mishchenko, University of Manchester, UK and Benjamin Piot, LNCMI Grenoble. Graphite is made out of a stacking of layers of carbon atoms arranged in a honeycomb lattice. This recurring pattern gets disrupted at the surfaces of the crystal which leads to the occurrence of “surface states” – fading waves [...]
