DISTRIBUTION OF THE LOCAL MAGNETIC-FIELD OF THE VORTEX LATTICE NEAR-THE-SURFACE OF AN ANISOTROPIC SUPERCONDUCTOR IN OBLIQUE EXTERNAL MAGNETIC-FIELDS

The distribution of the magnetic field in the unit cell of the Abrikos ov vortex lattice near the surface of a uniaxial, anisotropic, type-II superconductor in an oblique external magnetic field is determined on the basis of the London model for the cases in which the symmetry axi s is perpendicular and parallel to the boundary of the superconductor. The distribution of the local magnetic field is obtained as a functio n of the distance from the surface of the superconductor and the incli nation angle of the external field. It is shown for an YBaCuO high-T-c superconductor that the investigation of the distribution function of the local magnetic field as a function of the angle of the external m agnetic field relative to the symmetry axis and to the surface of the superconductor can yield important information about the anisotropic p roperties of the superconductor.
