We performed zero-field muon spin relaxation/rotation measurements on the electron-doped system Pr1-xLaCexCu1-yZn yO4 to study the impurity effect on spin correlations in both magnetic and superconducting phases. In the antiferromagnetic phase with x = 0.08, the Néel temperature TN decreases monotonically upon Zn substitution, while with approaching the superconducting boundary (x = 0.10), the effect of Zn substitution on the suppression of TN becomes weak (x = 0.08). In the superconducting phase, in contrast to the hole-underdoped system, suppression of superconductivity by Zn substitution neither enhance well-defined AF correlations nor induce it at least down to T = 6 K. The impurity effect is discussed from a viewpoint of dilution effect of the Zn on the Cu spin lattice.
