Description
The Physical Property Measurement System – PPMS is an automated low-temperature and magnet system for the measurement of material properties like specific heat, magnetic AC and DC susceptibility and both electrical and thermal transport properties (like Hall Effect, thermoelectric figure of merit and Seebeck Effect).
Further information
The temperature can be varied continuously between 1.9 K and 400 K, while a magnetic field of up to ±16 Tesla can be applied. The so-called Continuous Low-Temperature Control (CLTC) maintains temperatures below 4.2 K for indefinite periods of time and offers smooth temperature transitions when warming and cooling through 4.2 K.
User experiments with external instruments may automatically be controlled with the Visual Basic interface integrated within our Windows-based MultiVu control software or by controlling external Visual C++, Delphi or Visual Basic programs.
The base unit of the PPMS consists of a cryostat with a superconducting magnet coil. The different measurement options result from the use of different measurement inserts or sample holders and activating the according software mode. The optional EverCool II dewar features an integrated helium re-liquefier which makes the system virtually cryogen-free. Helium gas is only needed for purging the sample chamber.
