Finding Superconductors That Can Take the Heat

User rating: 3.5 / 5 after 14 vote(s)

By studying how superconductors interact with magnetic fields, Pitt researchers advance quest for higher-temperature superconducting materials.

Superconductors are materials with no electrical resistance that are used to make strong magnets and must be kept extremely cold-otherwise, they lose their superconducting abilities. Even the "high-temperature" superconductors discovered in the 1980s must be kept at around -300°F.
