Quantum Design PPMS® DynaCool™

The instrument uses a single two-stage Pulse Tube cooler to cool the superconducting magnet and the samples under study, providing a low vibration environment for electronic measurements. It employs a unique He-4 -based gas flow control system providing rapid temperature cycling and accurate temperature control. It also comes standard with an integrated Cryopump used to pump out the sample space to a vacuum of < 10-4 Torr. Features: Temperature range: 0.3 K – 400 K Magnetic field: ±14 Tesla. Electrical Transport Option (ETO): AC Resistance measurements (frequency range: 0.1 – 200 Hz), Hall Effect, I-V sweeps. Measurement sensitivity: a few nV; resistance range: a few μΩ to GΩ. Vibrating Sample Magnetometer (VSM): measuring static (DC) magnetic moment as a function of temperature or field. Can take small single crystals, thin films (can be oriented with applied field in- or out-of film plane), sintered polycrystalline pieces and loose powders.
