Description
We have investigated the viscosity of vortices in La2-xSrxCuO4 as a function of carrier doping from x = 0.07 to x = 0.20. We found that the optimally doped material exhibited the moderately clean nature (l ∼ ξ, where l is the mean free path of quasi-particles in the core and ξ is the GL coherence length (≅ core radius)), whereas underdoped materials show smaller viscosity, suggesting some changes exist in the condensate in the underdoped region
