Normal state resistivity of underdoped YBa2Cu3O7-d films and La2-XSrXCuO4 ultra -thin films in fields up to 60 T

Abstract We present the normal-state resistance of La 2-x Sr x CuO 4 thin films under epitaxial strain, measured below T c by applying pulsed fields up to 60 T. We compare these data with earlier data on YBa 2 Cu 3 O x thin films in the underdoped regime. The data are analyzed in terms of the recently proposed 1D quantum transport model and charge-stripe models. The high field data have been used to identify the new regimes and dimensional crossovers caused by the formation of stripes and their interplay with disorder.
