YBCO Films and Buffer Layers Grown on Ni-Cr-W RABiTS With a Pd Seed Layer

A buffer layer structure was epitaxially deposited by pulsed laser deposition on a Pd seed layer grown on non magnetic alloy. Structural analyzes performed by x-ray diffraction and EBSD show a good texture, with typical YBCO FWHM of about 5 and 8.5 for in-plane and out-of-plane orientations, respectively. About 300 nm YBCO films deposited by PLD on such a buffer layer structure, show typical values of critical temperature of about 89 K and a critical current density greater than 0.6 at 77 K and self field.
