Abstract

In order to study the degradation of critical temperature T_c for a coated conductor using nanorods, the relationship between T_c and nanorod shape was investigated by transmission electron microscopy for ErBa ₂Cu₃O_y(Er123) films with BaZrO₃(BZO) and BaSnO₃(BSO) nanorods. The dependence of T_c on the BZO or BSO content was different, however, the nanorods interface density dependence of T_c was the same for both. Thus, the interface density of the nanorods controls Tcof the nanorod-added films. The different degradation in Tcbetween the BZO and BSO nanorod-added films originated in differences in the nanorod diameter and density.
