Thermal Conductivity in DC Fields

The thermal conductivity of a material is a measure of its ability to conduct heat and is a powerful probe of material properties.

Thermal conductivity at low temperature is a powerful probe that can reveal details of the electronic structure of novel and quantum materials. For example, it can be used to study the energy gap of unconventional superconductors. At the Maglab, we offer thermal conductivity measurements up to 16 T at 2 K using the Quantum Design PPMS.

Compatible Magnets

Superconducting Magnets

Quantum design PPMS (SCM6 and SCM7) with ultra-high vacuum.

  • Rough vacuum: Approximately 10 Torr of He-4 exchange gas remains when the sample chamber is pumped and purged at room temperature.
  • Ultra high vacuum: The sample chamber is exposed to a cryopump when lower pressure (~ 0.1 mTorr) is needed to decouple a heat capacity platform from the rest of the sample environment.

  • Quantum Design Thermal Transport Option (TTO) puck
