Abstract: Bitter decoration observations of vortices in thin films of YBa2Cu3O7-delta with four different orientations of the c axis are reported. For moderate angles of the c-axis tilt relative to the film normal, theta = 30-degrees and 45-degrees, we find a greatly enhanced anisotropy, eta(theta), of the vortex magnetic dimensions, in comparison with even theta = 90-degrees in single crystals, which is attributed to the thickness dependence of the anisotropic penetration depth in films. Also, in contrast to single crystals, the anisotropy of the vortex arrangement is not proportional to eta(theta), in agreement with recent theoretical calculations.
