Description

The role of oxygen vacancies in the CuO2 plane was investigated in La1.82Sr0.18CuO4 by measuring the normal-state magnetic susceptibility. We found that the oxygen vacancies hardly affected the two-dimensional spin correlation when the reduction of the hole density was taken into account. In contrast, the superconductivity broke down much faster than the reduction rate of holes. (orig.)
