In both PPMS devices (physical properties measurement system, 9 T and 14 T) the critical current Ic and the critical current density Jc of superconducting samples can be determined by means of electrical transport current measurement. In addition, a variety of other measurement options are available:

  • Electrical transport (up to 2 A)
  • AC transport
  • Anisotropies by rotator
  • Heat capacity
  • Thermal conductivity
  • Thermal tripping
  • Vibrating Sample Magnetometer (VSM)
  • AC susceptibility

Due to the limitation of possible transport currents to 2 A, superconducting thin films and coated conductors usually have to be structured before installation. To measure unstructured superconducting samples, a split-coil magnet is available. Here, transport currents of up to 1000 A are possible in a magnetic field up to 6 T at temperatures between 2 and 100 K. Anisotropies can be determined using a rotator.
