Available measurement options include all required hardware and electronics to immediately begin collecting publication-quality data and the system is also easily adapted to custom user experiments.
Capabilities include:
- Sample environment controls include fields up to ±9 T and a temperature range of 1.9–400 K.
- Expandable design makes the PPMS the most versatile system of its kind.
Measurement Options:
- Measure DC resistance on up to three channels using the DC Resistivity Option
- Measure resistances of 10 μΩ–5 MΩ in a standard 4-probe configuration.
- Source currents between 2 nA–8DC Resistance.
- Configurable bridge parameters to limit the voltage, current, or power at the sample for protecting sensitive devices, films, etc.
- van der Pauw — Hall Transport
- Utilize a switching controller to automatically collect data necessary and accurately calculate parameters including carrier concentration and sheet resistance for uniformly thick samples of arbitrary shapes.
- Vibrating Sample Magnetometer (VSM)
- Measure a sample's magnetic moment as a function of temperature or magnetic field.
- Noise levels of less than 6·10-7 emu at 300 K.
- Heat Capacity
- Perform high-precision microcalorimetry experiments using the Heat Capacity option to measure a sample's heat capacity as a function of temperature.
- Measurements in a static applied magnetic field are possible using the automated field calibration function of the software.
- Typical addenda signal of 0.2 μJ/K at 2 K, where signal resolution is 2 nJ/K.
- Custom Built Experiments — For Advanced Users
- Multifunction probes provide an interface with the integrated chamber wiring and simplify the process of bringing external connections (electrical, optical, etc.) in from the top of the probe.
- A number of variants are available.
