Epitaxial YBa[sub 2]Cu[sub 3]O[sub 7[minus][delta]] thin films irradiated with swift heavy ions under different directions showed a strongly changed angular dependence of the critical current density [ital J][sub [ital c]]([ital B],[ital T],[var theta]) in the mixed state. Additional peaks, which dominate the angular dependence of [ital J][sub [ital c]], appear at angles where the magnetic field is parallel to the irradiation direction, due to the strong pinning of the introduced linear defects. Irradiated YBa[sub 2]Cu[sub 3]O[sub 7[minus][delta]]/PrBa[sub 2]Cu[sub 3]O[sub 7[minus][delta]] superlattices, however, reveal no additional [ital J][sub [ital c]] peaks but an isotropic [ital J][sub [ital c]] enhancement in a wide angular range. This contrary behavior could be explained by flux lines of different dimensionality.
