High-Tcsuperconductivity above 110 K in the Tl-Ba-Ca-Cu-O system

Abstract
High-Tc superconductivity above 110 K has been observed in Tl-Ba-Ca-Cu oxides. The dependence of electrical resistivity and AC magnetic susceptibility on temperature show that the zero-resistance transition temperature is about 114 K and a dramatic magnetic susceptibility drop appears at 117 K. The superconductivity remains stable after several cooling and heating cycles. The observation of superconductivity in this system was carried out at least eight times.
