Abstract
We report on magnetoresistivity rho(ab) (theta, H, T) measurements bel ow T(c) in YBa2Cu3Oxn films with differing oxygen content x(n). The ob served variations in the angular and field dependence of rho(ab) with reduced x(n) indicate a gradual dimensional crossover from an anisotro pic 3D to a quasi-2D behaviour. The increasing anisotropy is related t o a decrease of the coupling between the Cu2O2 bilayers when oxygen is removed from the Cu1O(x) chain-planes.
