Système de mesure des propriétés physiques (PPMS)
Quantum DesignLe PPMS est un système automatisé à basse température et sous champ magnétique pour la mesure des propriétés des matériaux comme la chaleur spécifique, la susceptibilité magnétique AC et DC et les propriétés de transport électrique et thermique (comme l'effet Hall, le facteur de mérite thermoélectrique et l'effet Seebeck).
- Effectue des mesures entièrement automatisées
- La conception modulaire offre une variété d'applications
- Plage de température de 1,9 K à 400 K
- Champ magnétique jusqu'à ±16 Tesla
- Option Cryogen Free disponible
Plus d'informations
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.

"We have a Quantum Design MPMS-XL-7 and a PPMS-14 system in our Neutron Scattering and Magnetism Laboratory, Institute for Solid State Physics, ETH Zürich. We have a number of inserts and add-ons, including the iQuantum 3He system and pressure cell for the MPMS, and VSM, dilution refrigerator and AC option for the PPMS. This equipment was installed by the technical service of Quantum Design GmbH in early 2010. The machines have been operating 24/7 from the moment of installation. Until now we have had no problems except for minor 'I should have read the manual' moments. The technical service in Darmstadt, their patience and diligent and fast service have been very useful for us. We are totally satisfied with the products, and have recently ordered an additional PPMS-9 system from Quantum Design."

"A Quantum Design PPMS-9 with reliquefier has been installed in February 2011 at our institute for Inorganic Chemistry at the Martin-Luther-University Halle-Wittenberg. A technician from Quantum Design GmbH set up the system. The PPMS is intensively used ever since its installation. I can highly recommend the reliquefier for users, who have difficulties in the supply of liquid helium. To date, the reliquefier has been running for about 10 000 hours of operation without any trouble. It reliably recondenses the evaporating helium without any significant loss."
