Abstract

Muon spin relaxation (μSR) measurements were applied to the Zn-substituted YBCO system, YBa2Cu3-2yZn2yO7-δ, around the hole concentration p = 1/8 per Cu in the CuO2 plane, and to the Ga-substituted LSCO system, La2-xSrxCu1-yGayO4 in the overdoped region. Enhancement of the muon-spin-depolarization rate was observed at low temperatures in both systems, indicating the enhancement of the magnetic correlation between Cu spins. Our μSR results on the Zn-substituted YBCO system suggest the existence of the so-called 1/8-effect also in the YBCO system. The results on the Ga-substituted LSCO system in the overdoped region are suggestive of the existence of a kind of a spin ordered state.
