N2 - Temperature dependence of superfluid densities ns(T) ∝ λ-2(T) of underdoped Bi2Sr2CaCu 2O8+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 2Cu3O7-δ suggests that this is a universal phenomenon in underdoped cuprates.
