Abstract We report the muon spin rotation experiments on Zn substituted La1-x Srx CuO4, for four zinc concentrations y=0.0,0.0025,0.005,0.01, at strontium concentrations x=0.15,0.20. We find that T_ c in the optimally doped (x=0.15) and overdoped (x=0.20) 2:1:4 decreases linearly with increasing zinc concentration. Plotted against the planar zinc concentration, the Tc’s of both series seem to fall on the same line. The superconducting carrier density/effective mass ratio, n_ s/m*, at first decreases linearly, rising above this line for higher zinc concentrations. This behavior may result from the localization of carriers in an area \xiab around each zinc atom.
