Normal state resistivity of underdoped YBa 2Cu 3O 7-d films and La 2-XSr XCuO 4 ultra-thin films in fields up to 60 T
Abstract
We present the normal-state resistance of La 2-xSr xCuO 4 thin films under epitaxial strain, measured below Tc by applying pulsed fields up to 60 T. We compare these data with earlier data on YBa 2Cu 3O 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.
