Quantum Design 9T "Red" PPMS Details
Clark Hall D22 (Primary Staff: Steve Kriske; Secondary Staff: Jon Shu)
The “Red” PPMS consists of a 9 Tesla superconducting magnet in a helium dewar with sample temperature range of 1.8-400 K. The numerous combinations of electrical measurements, magnetic fields, and temperatures allow for a multitude of measurements.
Possible Measurements
- Resistivity (DC or low-frequency AC)
- Hall Effect (DC or low-frequency AC)
- I-V curves and critical current measurement
- Rotating sample probe for >360-degree sample rotation in field (two rotational axes available)
- Open software architecture allows for additional types of electrical measurements
For electrical measurements, each sample is attached to a puck which has up to 12 electrical leads for performing measurements with built-in measurement options as outlined above, or with external instrumentation. The built-in Resistivity and AC Transport options provide a source current and measure the resulting voltage for simple measurements of resistance or Hall Effect. A sample rotator probe allows any of these electrical measurements with >360-degree sample rotation in the magnetic field, with rotation available in or perpendicular to the plane of a thin film sample.
