Photograph of the HTS-based split coil transverse magnet. Electrical connections to the magnet leads, as well as control wiring, are located on the top plate. The experimental probe, which includes an outside vacuum jacket, an annular gas flow region for temperature control, and the isolated sample chamber, inserts into the center of the magnet from the top.
Four-quadrant magnetization hysteresis loops of epitaxial film on a GaAs(001) substrate, as measured using the heated oven sample holder for the VSM. The ferromagnetism evident at is absent at . The magnetic field was ramped at a uniform rate of for both curves.
Comparison of cryogen costs for and LHe at various prices for each cryogen showing the and cumulative costs in US dollars. The daily cryogen consumption is based on typical and comparable usage of the temperature and field controls of each system.
