- 論文の詳細を見る
Hydrogen distributions of high temperature superconductor bulk and film material, YBaCuO and BiSrCaCuO, have been determined up to depths of 1 μm. In both annealed and non-annealed samples widely varying volume concentrations, from less than 0.1 up to more than 10 at.%, respectively, have been found. The preparation conditions of the films strongly influence the hydrogen content. Surprisingly, no correlation at all of hydrogen content with stoichiometry, structure and critical temperature is observed.
