Yttrium Barium Copper Oxide

Yttrium Barium Copper Oxide (YBa₂Cu₃O_7-δ or YBCO) is a perovskite structure that becomes superconducting below 90 Kelvin, a trait which interests scientists. This is above the boiling point of nitrogen which is cheaper than cooling methods for low temperature superconducters.
