1. Preparation, structure and properties of Hg, Tl-containing high-temperature superconductors
Sammanfattning : Powder samples with the general composition (Tl,Hg)2(Ba,Sr)2(Sr,Ca)Cu2O8-d, abbreviated 2212, were synthesised by solid-state reaction of metal oxides in closed silica ampoules. Depending on the relative amounts of Ba, Sr, and Ca, the superconducting transition temperature, Tc, varied significantly (45-100 K). LÄS MER
