Abstract

A new series of rare earth-niobate, RE3NbO7 (RE = Y,Gd,Eu), buffer layers were developed for the growth of superconducting YBa2Cu3O7-δ (YBCO) films on biaxially textured Ni-W (3 at.%) substrates. Using chemical solution deposition, smooth, crack-free, and epitaxial RE3 NbO7 (RE = Y,Gd,Eu) films were grown on cube-textured Ni-W substrate. YBCO film with a critical current density of 1.1 × 106 A/cm2 in self-field at 77 K was grown directly on a single Gd3NbO7-buffered Ni-W substrate using pulsed laser deposition.
