- 論文の詳細を見る
Field angular dependences of critical current density are measured for as-grown high crystalline quality ErBa2Cu3O7-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 $\mathbf{B} \parallel c$-axis of ErBa2Cu3O7-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.
