Magnetic properties for anisotropic d(x(2)-y(2))-wave superconductivity

Abstract

The single vortex structure is derived in the presence of applied magnetic field. According to our results, the winding number of the s-wave does not change regardless of the vector potential. The generic London equation for a d(x2-y2)-wave superconductor with mass anisotropy is expressed. By neglecting higher order terms, this work analyzes the magnetic-field distribution with and without a vortex. The interaction force between two parallel vortices is derived as well. Our results further reveal the presence of a torque between vortices irrespective of s- or d-wave order parameter, which is expected to vanish for isotropic cases. (C) 1998 Elsevier Science B.V.
