The division of Superconductivity and Magnetism of the Faculty of Physics and Earth Sciences of the University of Leipzig is concerned with the preparation and the characterization of superconducting, magnetic and carbon-based materials and the study of special phenomena found in these materials. We investigate their transport and magnetic properties both in thin films as well as in single crystals.
JW Player goes hereThis video shows the levitation of a permanent magnetic ring on a high-temperature superconducting ceramic pellet submerged in liquid nitrogen. Due to flux-line pinning properties and the torque exerted by the gravitational force the ring starts to oscillate slowly at the beginning till it fully rotates.
Highlights of the last years:
- Quantum Hall effect in bulk graphite
