We have fabricated Gd123 thin films with Ce and Zr added at the same time by the fluorine free metal organic deposition method. When different BMO3-type artificial pinning centers (APCs) are generated simultaneously, they considered to share the Ba used for APC growth. Therefore, it is expected that APCs size is more decreased. In this study, we selected Ce and Zr as doping elements, and fabricated three samples with the same amount of APCs added. As a result, the maximum pinning force density of the co-added sample was 1.6 times higher than that of the single BMO3 sample at 1T under77.3K.
