Abstract

A review is given of the impurity effect on the static spin correlations in lightly doped La_{2 - x} Sr_x CuO₄ studied by the neutron scattering technique. Zn doping reduces the incommensurability just slightly. On the other hand, Ni doping quickly reduces the incommensurability and restores Néel ordering, indicating a strong effect on hole localization. This suggests that Ni is doped as Ni^{3 +} or that doped Ni^{2 +} and hole form a strongly bound state with the Zhang-Rice character. It was found that this behavior is universal in a wide range of hole concentration in La_{2 - x} Sr_x CuO₄ (0.01 ≤ x ≤ 0.07).
