As Zn$^{2+}$ is substituted onto the Cu$^{2+}$-sites, an anomalous enhancement of the local spin susceptibility $\\chi^{\\prime\\prime}(\\omega)$ appears due to the emergence of a commensurate antiferromagnetic excitation centered at wave vector \\textbf{Q}$=(\\pi, \\pi, 0)$ that coexists with the known incommensurate SDW excitations at \\textbf{Q}$_{HK}=(\\pi\\pm\\delta,\\pi), (\\pi,\\pi\\pm\\delta)$.
