Scientists have discovered a new class of high-temperature superconductors.

This newest family of high-temperature superconductors consists of layers of a fluorine-doped rare-earth metal oxide (lanthanum or samarium) sandwiched between layers of iron arsenide.

These materials have little of no electrical resistance at temperatures far warmer than the near-absolute-zero temperatures are warmer than the near-absolute-zero temperatures required for earlier generations of superconductors. As the higher temperatures are easier to maintain, the higher the operating temperature, the more practical the superconductor will be, making high temperature materials desirable in the area of electronics.
