Abstract(in English) | By RF magnetron sputtering (001)-oriented CeO_2 buffer layers above 400 Å in thickness grow with (111)facet on R-Al_2O_3 substrates. EuBa_2Cu_3O_<7-δ> (EBCO) thin films are deposited with non-c-axis orientation on the CeO_2 buffer layer with (111)facet and exhibit poor superconducting properties. In the present work, we attempted to suppress (111)facet growth in thick CeO_2 buffer layer. By increasing deposition rate(R_d) under the optimum conditions, we were able to deposit facet-free CeO_2 buffer layers with uniformity and minuteness grains and CeO_2 buffer layers of 10000 Å were facet-free. EBCO thin films deposited on the thick CeO_2 buffer layer showed critical temparature(T_c)=91 K at the maximum. |
