摘要

Field angular dependences of critical current density are measured for as-grown high crystalline quality ErBa_2Cu_3O_(7-δ) films with BaZrO_3 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 BaZrO_3 nano-rods. The largest enhancement is observed in B ‖ c-axis of ErBa_2Cu_3O_(7-δ) films. This anisotropic critical current density enhancement is thought to be caused by the direction of BaZrO_3 nano-rods which grow along the c-axis of the films. BaZrO_3 nano-rods in the films will promise the application of coated conductors in a magnetic field.
