摘要：

Single-phase Tl2Ca1Ba2Cu2O 8 thin films with zero-resistance transition temperature up to 100 K have been prepared on single-crystal MgO substrates from codeposited Ca-Ba-Cu amorphous metallic alloy precursors. After thermal oxidation of the metallic alloy film, Tl from Tl2O3 was vapor deposited and diffused into the resulting mixed metal oxide during a rapid high-temperature anneal. The films prepared in this process are highly oriented with the c axis normal to the substrate.
