Research and infrastructure at the Dresden High Magnetic Field Laboratory

Since the beginning of 2007, the new Dresden High Magnetic Field Laboratory (Hochfeld-Magnetlabor Dresden, HLD) at the Forschungszentrum Dresden-Rossendorf, is accepting proposals for magnet time and is hosting user groups. Pulsed magnetic fields up to about 70 T (with 150 ms pulse duration in a 24 mm bore) as well as smaller ones (60-65 T, with 25-50 ms pulse durations) are available for users. Recently, the European record field of 87.2 T (10 ms in a 20 mm bore) has been reached in a newly designed double-coil system. Besides the ultimate goal of a pulsed magnet reaching 100 T for a timescale of 10 ms in a bore of 20 mm, further large-scale magnets (e.g. 60 T, 1 s, 40 mm) are planned. The necessary energy for the pulsed coils is provided by a world-unique 50 MJ capacitor bank. A free-electron-laser facility next door allows high-brilliance radiation to be fed into the pulsed field cells of the HLD, thus making possible unique high-field magneto-optical experiments in the range 4-250 µm. Cryotechniques and different sample probes for a broad range of experimental techniques, custom designed for the pulsed magnets, are readily available for users. In-house research of the HLD focuses on electronic properties of strongly correlated materials at high magnetic fields. Some examples of the scientific work being carried out will be highlighted.
