A new record for a trapped field in a superconductor could herald the arrival of materials in a broad range of fields.

Scientists working at the MagLab have made a breakthrough in identifying the state from which high-Tc superconductivity emerges. Their results are in the June 19th issue of the journal Nature.

Josephson vortices were unexpectedly observed in the high-temperature iron superconductor SmFeAs(O,F), despite the material’s low electronic anisotropy. This development is important for the future deployment in high-Tc cable technology.

A prototype high-temperature superconducting coil for the 32 T all-superconducting magnet was constructed with YBCO tape and successfully tested in the large-bore resistive magnet at the MagLab.
