Abstract

In order to study the degradation of critical temperature Tc for a coated conductor using nanorods, the relationship between Tc and nanorod shape was investigated by transmission electron microscopy for ErBa 2Cu3Oy(Er123) films with BaZrO3(BZO) and BaSnO3(BSO) nanorods. The dependence of Tc on the BZO or BSO content was different, however, the nanorods interface density dependence of Tc 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.
