Notes:
Non-Rutherford elastic resonance scattering, 16O(α,α)16O at 3.045 MeV, has been used to measure the change in relative oxygen content, δ of dc-sputtered YBa2Cu3O7−δ (YBCO) films due to postdeposition annealing to a precision of 1%. Experimental results show that only 3.4% of the total amount of oxygen in YBa2Cu3O7−δ is absorbed in the postdeposition annealing process, and this agrees with our x-ray diffraction data. The presence of oxygen during annealing, which leads to the transition to the superconducting orthorhombic structure, may also be understood as providing a more favorable environment for structure reformation, rather than only adding more oxygen into the YBCO film. © 2001 American Institute of Physics.
