摘要：

We report evidence for the reduction of long range lattice order caused by slight departures from the optimal growth temperature in fully doped (x≈0.9) YBa2Cu3O6+x films deposited by ion-beam sputtering on 〈001〉 SrTiO3. We estimate the characteristic length of this disorder from the broadening Δ of the 〈005〉 x-ray diffraction rocking curve. The depression of superconductivity and normal conductivity scales as Δ and disappears when the in-plane lattice coherence length rc∼1/Δ is larger than ≈10 nm.© 1995 American Institute of Physics.
