Abstract

Systematic neutron scattering measurements have been performed on the Sr-doped La_2-xSr_xCuO₄ to study the doping dependence of spatially modulated dynamical spin correlations or so-called incommensurate spin fluctuations. The modulated spin correlations appear beyond x≈0.05 which is close to the lower boundary of the superconducting phase. First evidence was observed for the linear relation between the degree of spatial modulation or the incommensurability δ(x) and the maximum T_c at x. We present a universal curve for δ(x) by adding data from other La₂CuO₄ systems such as oxygen-doped superconductors, oxygen-reduced or Zn-substituted nonsuperconductors, and La_1.6-xNd_0.4Sr_xCuO₄.
