Abstract
A correlation between flux-pinning characteristics and stacking faults (SFs) formed by Sm substitution on Y and Ba sites was found in Sm-doped YBCO films. It was confirmed that 223 type SFs, Y2Ba2Cu3Ox, composed of Y and O extra planes aligned parallel to the ab-planes were formed via Sm substitution on the Y site and increased in number with increased Sm doping on the Ba site. The number density of 223 SFs is correlated strongly with the enhancement in ab-plane correlated flux-pinning, resulting in a sharpening of the H ab peak in the curve of Jc as function of magnetic field orientation.
