High magnetic fields are one of the most powerful tools available to scientists for the study, modification, and control of the state of matter. Making highest magnetic fields available for scientists, the Dresden High Magnetic Field Laboratory (Hochfeld-Magnetlabor Dresden, HLD) at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has opened its doors for external users in 2007. The laboratory recently has achieved a record field of 94.2 T having the ambitious goal of reaching 100 T on a 10 ms timescale. In the pulsed magnets, a variety of experimental methods are available allowing to measure e.g. electrical transport, magnetization, magnetostriction, ultrasound, ESR, and even NMR with very high resolution. As a unique feature, 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 high-field magneto-optical experiments in the range from 3 to 250 µm. In-house research of the HLD focuses on electronic properties of strongly correlated materials at high magnetic fields. This includes the investigation of strongly frustrated magnetic materials, the determination of the doping-dependent evolution of the Fermi surface of electron-doped high-temperature superconductors by use of quantum-oscillation measurements, as well as the recently found evidence for the existence of the Fulde‑Ferrell‑Larkin‑Ovchinnikov state in organic superconductors.
