Excatly! Even the superconductor itself is YBCuO, which has been well known since 1986. It's the first "Type 2" superconductor to have been discovered.
It may be the first high-temperature superconductor discovered. Type II superconductors go back to the 1930s. (I worked with Nb3Sn samples when I had a summer job at Gulf General Atomic in 1969.)
