Abstract
The observed increase of superconducting transition temperature (Tc) with the number of copper oxide planes continues in the four-[CuO2]-2 layer (single TI layer) oxide superconductor, which has been prepared with > 80% purity and was magnetically aligned for crystallographic identification. A master scaling curve is proposed, which ties together the Tc's of virtually all known Bi and Tl oxide superconductors, and shows that the Tl(Bi) layers play an essential role in the superconductivity. publication 350 of the Barnett Institute.Keywords
