Abstract
Thin films of Er-Ba-Cu-O system with various thickness have been prepared on R-plane of sapphire by rf-magnetron sputtering. As-sputtered films thicker than 0.15 µm showed superconductivity. As the thickness of the films increased, the transition width decreased and the critical current density increased. As-sputtered film with 1-µm thickness exhibited superconducting transition at onset temperature of 91 K and the zero-ρ state was observed below 80 K.Keywords
