Zinc diffusion in YBa2Cu3O7−x ceramics

Interdiffusion of rare-earth cations in Ln1−x ′Ln x ″ Ba2Cu3O7 − δ (Ln′, Ln″ = Y, Dy, Ho) High-T c superconductors

“…[2][3][4]), whereas there is limited information about cation diffusion in this type of high T c material. There are reports on nickel [5][6][7], indium [7], tin [7], zinc [8], copper [9,10], and rare earth [11] self diffusion in the yttrium barium cuprate YBa 2 Cu 3 O 7 -δ . Data on interdiffusion of rare earth cations in Ba 2 Cu 3 O 7 -δ super conducting cuprate solid solutions are not available in the literature.…”
