Recently, high-temperature, superconducting coated conductors (CCs) are being used for various applications, and further improvement of the in-field transport property is required. In order to improve the magnetic field and angular dependences, introducing artificial pinning centers (APC) into the superconducting layer is known to be effective. Moreover, it is necessary to fabricate long CCs while maintaining excellent properties in order to reduce manufacturing costs. We succeeded in achieving the above-mentioned issues by using trifluoloacetate solution metal organic deposition (TFA-MOD), and fabricated a long Y0.77Gd0.23Ba2Cu3Oy (YGdBCO) + BaZrO3 (BZO) CC using batch furnace heat treatment. We also confirmed the superior infield performance of this CC through transport measurements.
