Artificial pinning centers (APC) for trifluoroacetates-metal organic deposition (TFA-MOD) Y_1-xSm_xBa₂Cu₃O_y (YSmBCO) coated conductors were introduced to enhance J_c under the magnetic fields and improve the magnetic field angular dependence of J_c. The coated conductors showed high self-fields J_c values (J_c^s.f.) of 3.8 MA/cm² and a J_c minimum value of 0.53 MA/cm² at 77 K and 1 T. Moreover, the coated conductors have isotropic J_c-B-θ properties with the ratio (J_c,min/J_c,max) of 0.91 (77K, B=1 T). From the results of microstructural observation, BaZrO₃ (BZO) nanoparticles were uniformly dispersed in the films by introduction of Zr-salt into the YSmBCO metallic organic solution. The nanoparticles were dispersed uniformly not only along the lateral direction (B//ab) but also along the normal direction to the tape (B//c). It is believed that the uniform dispersion of BZO nanoparticles in TFA-MOD REBCO coated conductors may act as flux pinning centers to enhance the J_c independent from the angle of the applied magnetic fields.
