Abstract

Temperature dependence of superfluid densities n_s(T) ∝ λ^-2(T) of underdoped Bi₂Sr₂CaCu ₂O_8+x (Bi2212) films are measured. Transition temperature of these films varies from 80K near optimal doping to 12K for severely underdoped ones. T-dependence of superfluid density gradually loses its sharp downward curvature with underdoping. Similar behaviour seen in YBa ₂Cu₃O_7-δ suggests that this is a universal phenomenon in underdoped cuprates.
