Dresden High Magnetic Field Laboratory
(1)The Dresden High Magnetic Field Laboratory (Hochfeld-Magnetlabor Dresden, HLD) focuses on modern materials research in high magnetic fields. High magnetic field experiments are the ideal way to gain insights into the matter that surrounds us. Magnetic fields allow for the systematic manipulation and control of material properties – which is why these kinds of experiments are conducted on new materials so that their fundamental properties can be explored and so that they can be optimised for future application.
In particular, electronic properties of metallic, semiconducting, superconducting, and magnetic materials are investigated. Work is being carried out on exotic superconductors, strongly correlated systems, low-dimensional and frustrated magnetic as well as nanostructured materials.
The institute conducts research in the programme From Matter to Materials and Life(2).
Scientific ProfileThe HLD is also engaged in the development of novel experimental techniques including resonant methods as ESR and NMR each modified for the use in high pulsed magnetic fields. Unique in the world, the free-electron lasers(4) (FELs) of the neighboring superconducting electron accelerator ELBE(5) can be used in combination with high-field magnets for magneto-optical experiments. The Hochfeld-Magnetlabor Dresden is operated for in-house research and as a user facility as well.

The research on frustrated magnetic spin systems is one of our scientific main targets. Materials with competing spin-spin interactions form a plethora of scientifically appealing spin configurations. Excited states of such magnetic ground states are in the focus of interest of modern solid-state physics. Their understanding is one of the major challenges and driving stimulus of modern materials research. In this context, we actively participate in the 'Collaborative Research Center 1143(7)' of the Deutsche Forschungsgemeinschaft (DFG) as well as in the proposed cluster of excellence 'Center for Topological Quantum Matter (ct.qmat)(8)'. Along with the TU Dresden as well as other research institutions in Dresden, we address the working theme "Correlated Magnetism: From Frustration To Topology".
For the generation of high pulsed magnetic fields, a development program for pulsed magnets and pulsed power supplies is being carried out. The HLD is engaged to open the access to magnetic fields up 100 T. For this purpose, a development program for pulsed-power supplies providing electrical currents of several 100 kA as well as electrical power of several GW is in work. These technological activities which make also use of modern simulation methods based on finite elements are under way with respect to industrial applications, e. g. for electromagnetic pulse forming, joining, and welding as well as for medical engineering.
The Dresden High Magnetic Field Laboratory has been extended as an international user facility during 2011 - 2013. It has received a new capacitor bank and six additional magnet cells to meet the large demand for measuring time in the highest magnetic fields. By that, the available magnet time has been doubled.
