We have investigated current transport property in Gd1Ba 2Cu3O7 δ coated conductor with artificial pinning centers in a wide range of temperature, magnetic field, B up to 27 T, and field angle. Due to the additional c-axis correlated pins, critical current density, Jc in B//c was enhanced and the improvement was observed in wide range of B. On the other hand, around Bc below 65 K, the angular dependence of nvalue showed a valley-like behavior, although the Jc was increasing. In addition, the temperature dependence of the pinning force density defined as Jc × B was not scaled on an expected master curve. These results indicate the pinning in Bc is governed by different mechanism below 65 K and high magnetic field.
