Estimation of the Doping Dependence of Antiferromagnetism in the Copper Oxide Material
Within the - 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 for a reasonable parameter
value , which is in agreement with the experiments on copper oxide
materials.Comment: 14 page
