Research area: Highly correlated electron systems

The Dresden High Magnetic Field Laboratory (Hochfeld-Magnetlabor Dresden, HLD) focuses on modern materials research in high magnetic fields. 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 magnetic materials as well as nano stuctures on anorganic and organic templates. As examples, two highlights are presented in the  article 'Highest magnetic fields' of the annual review 2006 of FZD. These are the observation of a quantum-phase transition in the exotic halfmetal CeBiPt as well as the observation of antiferromagnetic ordering in the organic compound [Cu(HF2)(pyrazine)2]BF4.

Experimental techniques at the HLD:

The 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-electronen lasers (FELs) of the neighboring superconducting electron accelerator ELBE 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.

Advanced technology at the HLD:

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.
