The European Magnetic Field Laboratory was created to unite high magnetic field work throughout Europe at the Dresden High Magnetic Field Laboratory (Germany), the Laboratoires National des Champs Magnétiques Intenses in Grenoble and Toulouse (France), and the High Magnetic Field Laboratory in Nijmegen (The Netherlands).

Nuclear magnetic resonance is a very powerful technique to look inside solids to study their electronic and magnetic properties. In general, the higher the magnetic field, the more information can be obtained about the material under study. Often a strong magnetic field induces a new state of matter and EMFL scientists have now succeeded in observing a new magnetic field induced state in the magnetic material LiCuVO4 by NMR at record magnetic fields up to 56 Tesla.
The shape of nanovesicles – called ‘polymersomes’ in jargon – in a solution varies at different compositions of that solution, scientist Roger Rikken and his colleagues at Radboud University discovered. “Besides the spherical shapes, we can create disks, rods, and bowl shaped stomatocytes by varying the ratio of the solvent. This regulates the osmotic pressure and permeability of the vesicles, controlling their deflation and subsequent re-inflation,” Rikken explains.
It may become significantly easier to design electronic components in the future. Scientists at the Max Planck Institute for Chemical Physics of Solids have discovered that the electrical resistance of a compound of niobium and phosphorus increases enormously when the material is exposed to a magnetic field. This giant magnetoresistance, which is responsible for the large storage capacity of modern hard discs, was previously known to occur in some complexly structured materials. Niobium phosphide or a material with similar properties which can be manufactured more easily could offer an alternative.
