摘要：

We have studied the doping dependence of the in-plane and out-of-plane superfluid density rho(s)(0) of two-monolayer high-T-c superconductors, HgBa2CuO4+delta and La2-xSrxCuO4, using the low-frequency ac susceptibility and the muon-spin-relaxation techniques. For both superconductors, rho(s)(0) increases rapidly with doping in the underdoped and optimally doped regimes and becomes nearly doping independent above a critical doping, p(c)similar to0.20.
