Electrical transport

Both AC and DC transport can be measured in any of the available pulsed magnets in the temperature range from 400 K down to 500 mK.

The standard sample holder can accommodate up to three samples when both longitudinal resistivity and Hall effect are measured.

The maximum sample space available is 10 x 6 x 2 mm. Angular-dependent measurements can be performed on two samples simultaneously, however restricting their size to 4 x 3 mm.

Typical AC-excitation currents range from 1 μA to 100 mA with frequencies between 2 and 200 kHz. 

Relative resolutions of 10-4 are achieved.
