ABSTRACT:
A method for producing a high temperature superconductor system having the composition TlBiBaCaCuO. The system exhibits a T.sub.c of at least 116 K. The method includes the steps of mixing compounds including Tl, Bi, Ba, Ca, Cu, and O to create a mixture. The mixture is heated. The mixture is then cooled.
