Abstract (in Japanese) (See Japanese page) 
(in English) We have fabricated a Bi2Sr2CaCu2O8+x(Bi-2212) thin film on a MgO substrate by the metal-organic decomposition (MOD) method to apply the film to high frequency devices such as a terahertz oscillator and detector. However, in order to apply the film to devices flexibly, it is important to evaluate the characteristics of the film with changing the thickness. In this study, we optimized a firing condition for Bi-2212/MgO thin films with the thickness from 40 to 240 nm by MOD and investigated the characteristics of the films. As a result, for the film with about 120 nm fired at 840℃, a rotation angle = 45 deg was dominant. On the other hand, for the film with about 240 nm fired at 845℃, ~±12 deg. were dominant. When increasing the film thickness, a surface morphology improved, the resistivity at on-set Tc decreased, and the critical current density (Jc) increased. Jc was 4~5×105A/cm2 at 4.2K for the films with 120 and 240 nm.
