Abstract
Tl‐Ba‐Ca‐Cu‐O superconducting thin films with zero‐resistance temperatures up to 115 K have been prepared using a Tl2 O3 vapor process on Ba‐Ca‐Cu‐O precursor thin films. The Ba‐Ca‐Cu‐O thin films were made by laser deposition on Y‐stabilized ZrO2 substrates. This technique minimizes problems caused by the toxicity of Tl2 O3, and its subsequent decomposition to the volatile and toxic Tl2 O upon heating. Therefore, it may have practical application in the fabrication of high Tc Tl‐Ba‐Ca‐Cu‐O superconducting thin‐film devices.Keywords
