dc.description.abstractStrong flux pinning and a pronounced asymmetric angular dependence of J[subscript c]([eta, theta]) have been discovered in YBa[subscript 2]Cu[subscript 3]O[subscript 7—chi] films grown on miscut, mosaic LaAlO[subscript 3] substrate surfaces. A new pinning peak, which at low fields is nearly as strong as the “intrinsic pinning,” is observed for magnetic field orientations between the c axis and the CuO[subscript 2] plane. Cross-section transmission electron microscopy reveals columnar growth defects (2–3 nm diameter) aligned near the c axis, in concentrations ~10[superscript 10] cm[subscript —2]. The results demonstrate that deliberately modified substrate surfaces may introduce technologically useful flux pinning in YBa[subscript 2]Cu[subscript 3]O[subscript 7—chi] films.en
