Many techniques have been coupled with our pressure cells, which can be used in both DC and pulsed field environments at temperatures from 7 mK to 300 K with full rotation capability for most of the techniques. Techniques have also been developed to make contacts to very small samples for standard 4-probe and Hall Effect studies, but we also have a contactless technique that allows us to resolve SdH quantum oscillations in samples as small as 20 x 20 x 20 µm3. The staff works closely with the users months in advance of magnet time to be assure that publishable data is obtained. Measurements using high pressure in pulsed fields are also available at the MagLab.
