Science and Infrastructure at the New Dresden High Magnetic Field Laboratory

At the Forschungszentrum Dresden-Rossendorf the Dresden High Magnetic Field Laboratory (Hochfeld-Magnetlabor Dresden), HLD, has opened his doors for users since the beginning of 2007. Pulsed magnetic fields up to 70 T (with 150 ms pulse length in a 24 mm bore) as well as smaller ones (60-65 T, with 25-50 ms pulse lengths) are available for users. Further pulsed magnets with ever increasing performances are being continuously developed, having set the ambitious goal of reaching 100 T on a 10 ms time scale. A 60 T magnet with a 1 second pulse length is ready to be tested allowing thermodynamic experiments to be performed. At the HLD a world-unique experimental infrastructure is at hand with next-door free electron lasers making possible unique high-field magneto-optical and ESR experiments in the range 4-230 µm. Besides the user-lab activities a strong in-house research program is persued at the HLD. Thereby, the focus is laid on the investigation of correlated electron systems at high magnetic fields. This covers e.g. the recently found clear thermodynamic evidence for the existence of the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state in a layered organic superconductor [1] and the determination of the band- and angle-resolved superconducting coupling strength in the borocarbide superconductor LuNi₂B₂C [2].
