High Tc Y-Ba-Cu-O thin films by ion beam sputtering
Abstract
High quality Y-Ba-Cu-O thin films were successfully prepared by using ion beam sputtering. Zero resistance was reached at 90 K. The critical current density at 77 K was 4-5×104 A/cm2. The surface morphology of the films was observed by scanning electron microscopy.
