YBa 2 Cu 3 O 7−δ (YBCO) films with thicknesses ranging from 1.0 to 6.4 μm were deposited by pulsed laser deposition on rolling‐assisted biaxially textured substrates (RABiTS). The RABiTS were of the configuration CeO 2 /YSZ/Y 2 O 3 /Ni–3 at.% W. As the YBCO film thickness increased, I c continued to increase and reached ∼300 A/cm width for a 4.3 μm‐thick YBCO film. Commonly observed mechanisms for J c decrease with increasing YBCO film thickness were not observed. Homogeneous microstructures obtained in even the thickest YBCO films, suggest that the I c /width can still be enhanced considerably.
