摘要：

Using muon spin rotation (mu SR) we searched for evidence of Zn-induced magnetic moments in underdoped cuprates. We find that the moments, which in a previous mu SR stady were reported to be Zn induced, exist already in the pure underdoped compound and most likely arise from antiferromagnetic correlated Cu(2) spins. We obtain no evidence for additional Zn-induced moments. Nevertheless, we cannot exclude the possibility that Zn-induced magnetic moments exist in case they are very weakly coupled to the spin system and the mobile charge carriers of the CuO2 planes.
