The basal plane transport critical current density J{sub c} of YBCO epitaxial thin films is strongly anisotropic, leading to large enhancements of J{sub c} when H is precisely parallel to the copper-oxygen planes. Experimental evidence shows that the enhancement is a bulk phenomenon, and the orientation dependence is compared with a model of intrinsic flux pinning'' by the layered crystal structure. 7 refs., 2 figs.
