Abstract

Low surface resistance is achieved by introducing BaZrO₃ nano-particles in high crystalline quality ErBa₂Cu₃O _7-δ films. The surface resistance of a ErBa₂Cu ₃O_7-δ film with BaZrO₃ nano-particles grown by pulsed laser deposition is 55% of that without BaZrO₃ nano-particles near 65 K. This result suggests that the ErBa₂Cu ₃O_7-δ films with BaZrO₃ nano-particles have potential as high power microwave emitting devices. A new direction is shown for reducing the surface resistance of superconducting films.
