Physical Property Characterization

Physical property measurement system (PPMS)


The PPMS system (QuantumDesign, is based on a liquid He cooled dewar, containing a super-conducting magnet and a measuring probe. A variety of magnetic, electrical and thermal properties can be measured from 4 K to slightly above room temperature using different measurement systems.

Impedance measurement system

Impedance analyzer

The system is based on a Solartron 1260A impedance analyser that is controlled via a GPIB interface by PC. It is intended for ionic conductivity measurements of disc-shaped samples with ion-blocking metal electrodes and resistances between ca. 5 Ω and 1 MΩ. The frequency range is 10µHz to 32 MHz and applied ac voltages are up to 1 V.
