MAGNETIC-PROPERTIES FOR ANISOTROPIC D(X(2)-Y(2))-WAVE SUPERCONDUCTIVITY

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