Magnetic fields tune the ground state of quantum materials in a reversible and non-invasive way. Typical measurements include upper critical fields and vortex dynamics in high temperature superconductors, magnetoresistance in magnetic materials, tuning quantum critical systems in heavy fermion matter, or quantum oscillation experiments. In addition to our high-field work in collaboration with the National High Magnetic Field Laboratory (NHMFL), we operate superconducting laboratory magnets for intermediate to low field projects.
At the moment, we operate the following magnet system:
Johann der Beständige – 8T, 2″ bore. The system will be equipped with a vibration dampened variable temperature insert (1.5K-300K) for low-noise measurements of magnetoresistance and thermodynamic quantities such as the elastic modulus.
August der Starke – 16T, 1″ bore (exp. April 2016). Our flagship magnet will be equipped with straight probe sticks for high-frequency measurements, a high-precision rotator, and a Helium-3 insert to extend our temperature range to 280mK.
