We estimated the spread of the magnetically enhanced regions (wipeout regions) around Zn ions in high-Tc superconductors YBa2(Cu1-xZnx)4O8 (x=0, 0.005, 0.01, and 0.022) at T=4.2 K, via the planar 63Cu nuclear spin-lattice relaxation study with Cu nuclear quadrupole resonance (NQR) spin-echo technique. From the analysis of nonexponential planar Cu nuclear spin-lattice relaxation curves, we found that the wipeout region per a Zn ion shrinks with Zn doping in the superconducting state. The shrinkage is associated with suppression of the host antiferromagnetic spin correlation, as a result from a dilution effect on the magnetic CuO2 network.
