Y-{\rm x}\hbox{Gd}-{(1 - {\rm x})}\hbox{Ba}-{2}\hbox{Cu}-{3} \hbox{O} \rm y coated conductors (CCs) with artificial pinning centers (APCs) were fabricated by the trifluoroacetates-metal organic deposition method using a batch heat-treatment process. This process has been industrially applied to fabricate long superconducting tapes that have high critical current (I-{\rm c}). From the viewpoint of applications, the characteristics in magnetic fields become further important, and one solution has been shown previously as introduction of APCs such as BaZrO 3 . We applied the technique to our CCs fabrication process. The heat-treatment conditions, specifically total gas pressure, oxygen concentration, and crystallization temperature, were optimized for the batch heat-treatment process. As a consequence, fabricated CC showed extremely high characteristic J c value of 3.5 MA/cm 2 in self field, and 0.3 MA/cm 2 at 3 T in liquid N 2 . Moreover, by cross-sectional transmission electron microscopy observation, it was confirmed that the APC was distributed uniformly. Furthermore, the anisotropy of the pinning center is also examined based on the evaluation result of the angular dependence of J c in 3T.
