抄録

In oxide-based superconducting thin films, conceivable factors that give rise to a pinning center include dislocations, precipitates, twin boundaries, and a-axis-oriented phases. In this study, crystalline defects were created perpendicular to a high-Jc Sm1+xBa2-xCu 3Oy film surface during a film deposition process. We obtained extremely high Jc values, Jc = 0.37 MA/cm 2 (77 K, B // c, B = 5 T) and JC = 0.1 MA/cm2 (77 K, B // c, B = 8 T). These values are equal to or exceed that of the previously reported NbTi wire material measured in a high magnetic field at 4.2 K.
