Description

Bi-epitaxial heterostructures YBa2Cu3O x(YBCO)/CeO2/NdGaO3 were prepared on tilted-axes NdGaO3 substrates using laser ablation technique. The heterostructures were patterned for electrical measurements using photolithography and ion-beam milling. Electrical anisotropy of the YBCO film was tested on the ion-beam etched surface. Bi-epitaxial junctions with four different orientations of the bi-epitaxial border were fabricated and studied. The measured I V curves showed flux-flow behavior with critical current density 2.5 x 104 A/cm2 for the twist-type junctions and 1.5 x 103 A/cm2 for [1 0 0]-tilt type junctions
