Diffuse scattering streaks or bands have been observed in electron diffraction photographs for samples belonging to the superconducting system Ba/sub 2/YCu/sub 3/O/sub 7-//sub x/ (0less than or equal toxless than or equal to1). In-situ experiments show that this diffuse scattering can be associated with short-range ordering of oxygen vacancies. The same vacancy ordering occurs in previously reduced samples. Three types of diffuse scattering are observed, each corresponding to a short-range-order scheme.
