We describe a method for forming a nanoparticle dispersion in YBa₂Cu₃O7 superconducting lms grown by metal-organic depositionon RABiTS substrates. Two separate precursor modications have been shown by transmission electron microscopy to give nanopar-ticles of (Y,Dy)₂O₃ and BaZrO₃ with size distributions of 10-50 nm and 10-25 nm, respectively and that are well dispersed in the lm.These particles are eective ux pinning centers and enhance the transport critical current by up to 100% at 77 K for a magnetic eld of 1.5 T applied perpendicular to the tape. The processing required to grow these lms is not greatly altered from that of unmodied YBCO and can be readily transferred to continuous processing of long-length wires.
