Effect of La3+ substitution for Sr2+ on thephase formation, structure and properties of (Tl0.5Pb0.5)Sr2Ca2Cu3Oy compounds
Optimization of the hole concentration in (Tl0.5Pb0.5)Sr2Ca2Cu3 Oy (Tl-1223) was attempted though partial replacement of Sr2+ by La3+. Nine samples with nominal composition (Tl0.5Pb0.5)Sr2-xLax Ca2Cu3Oy were prepared, with x varies from 0 to 2. Magnetization measurements as a function of temperature...
