Quantum Design PPMS Dynacool

The Quantum Design Physical Property Measurement System (PPMS) is a flexible, user-friendly environment for performing measurements of various material properties  over a range of temperatures and applied magnetic fields. The PPMS instrument in the Illinois MRL are cryogen-free DynaCool models with superconducting solenoid magnets, allowing for continuous measurements over the temperature range 1.8K <  T <  400K and in fields 0 < H < 90000Oe. Together, the systems are equipped with options for measuring electrical transport, thermal transport, magnetic torque  and heat capacity. A horizontal rotator option allows for the sample to be rotated with respect to the applied field axis while performing resistivity measurements. A helium-3 insert extends the accessible temperature range to 0.4K < T < 400K for resistivity and heat capacity measurements.
