A new biaxially textured tape of Ni–0.1%Mn was used as a substrate for YBCO coated conductor through the RABiTS approach. Multi-layer CeO2/YSZ/Y2O3 buffer layers and YBCO film were deposited on the substrate by pulsed laser deposition. The deposition conditions of the buffer layers and the YBCO film were studied and compared. Biaxial textures have been obtained for buffer layers on Ni–0.1%Mn substrates. The YBCO films were deposited at two different deposition rates, corresponding to two different laser repetition rates, 10 and 200 Hz, respectively. The relationship between the Jc and the thickness of YBCO film was studied. AFM was used to examine the surface morphology and roughness of the YBCO films. The best Jc of YBCO films on these metal substrates was 2.3 × 106 A/cm2 at 77 K, 0 T.
