Abstract
The main consequences of the existence of an anisotropic order parameter within the basal planes in YBa2Cu3O7 are analyzed. It is shown that the superconducting condensate is sensitive to the different orthorhombic domains of the underlying crystal lattice. Hence, boundaries influence the electromagnetic properties in the superconducting state. Flux pinning, critical currents, and deflection of supercurrents by twin boundaries are analyzed semiphenomenologically.
