摘要：

Field angular dependences of critical current density are measured for as-grown high crystalline quality ErBa2Cu3O7-delta 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 vertical bar vertical bar c-axis of ErBa2Cu3O7-delta 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.
