Abstract
Within the $t$-$J$ model, we study the doping dependence of antiferromagnetism in the copper oxide materials by considering quantum fluctuations of spinons in the random-phase-approximation. The staggered magnetization vanishes around doping $δ=5%$ for a reasonable parameter value $t/J=5$, which is in agreement with the experiments on copper oxide materials.
