The effect of static vacancies that eliminate local Cu{sup 2+} spins has been studied in both the antiferromagnetic and superconducting state of La{sub 2{minus}{ital x}}Sr{sub {ital x}}CuO{sub 4}. Static vacancies induce uncompensated magnetic moments and suppress the three-dimensional Neel state much less effectively than mobile vacancies. Analysis of magnetic susceptibility provides accurately the Cu{sup 2+} magnetic moment ({similar to}1{mu}{sub {ital B}}), which is insensitive to Sr doping, indicating that the {ital d} state of Cu{sup 2+} remains highly localized upon the introduction of mobile vacancy.
