An AI has found the best Iron-based high-temperature superconductor

[John Clark]

Iron based Superconductors are better than conventional Niobium-Tin superconductors because they work at higher temperatures and in stronger magnetic fields , and they're better than copper based high temperature superconductors that were discovered about 30 years ago because they stop working in moderately strong magnetic fields. An AI has found the best Iron-based high-temperature superconductor anybody has discovered, it's a compound made of the common elements Iron Barium Arsenic and Potassium. It can produce a magnetic field of over 50 Tesla, more than twice as strong as the best low temperature Niobium Superconductor and the best previous Iron superconductor.
