Magneto Transport Setups

For investigation of superconductors, 2 dimensional electron systems, quantum phenomena and new magnetic materials often low temperatures and high magnetic fields are needed. For these measurements the group has several 4He, one 3He and one 3He/4He-dilution refrigeration cryostat. The magnetic fields range up to 15T. Typical measured properties are:

  • temperature and magnetic field dependence of the resistivity,
  • Hall effect,
  • Shubnikov-deHaas quantum oscillations,
  • thermopower,
  • Spin Seebeck effect,
  • tunneling spectroscopy
