Abstract

Field angular dependences of critical current density are measured for as-grown high crystalline quality ErBa₂Cu₃O _7-δ films with BaZrO₃ nano-rods. Large critical current density enhancement is observed. The magnetic field where the enhancement is observed coincides with the matching field calculated from the density of BaZrO₃ nano-rods. The largest enhancement is observed in B || c-axis of ErBa₂Cu₃O_7-δ films. This anisotropic critical current density enhancement is thought to be caused by the direction of BaZrO₃ nano-rods which grow along the c-axis of the films. BaZrO₃ nano-rods in the films will promise the application of coated conductors in a magnetic field.
