Cu nuclear quadrupole resonance has been used to investigate the effect of nonmagnetic Zn and magnetic Ni impurities on the normal-state properties in the underdoped YBa2Cu4O8 superconducting cuprate. We find that, in contrast to measurements on optimally doped YBa2(Cu1-zZnz)(3)O7-delta, there is no evidence of a complete local suppression of the antiferromagnetic correlations about the Zn impurity. There is also no evidence of Ni locally affecting the antiferromagnetic correlations. These results have important implications for superconductivity theories that assume a local suppression of the antiferromagnetic and superconducting correlations. [S0163-1829(99)13325-3].
