The vortex structure of (Formula presented)-wave superconductors is microscopically analyzed in the framework of the quasiclassical Eilenberger equations. If the pairing interaction contains an s-wave ((Formula presented)-wave) component in addition to a (Formula presented)-wave component, the s-wave ((Formula presented)-wave) component of the order parameter is necessarily induced around a vortex in (Formula presented)-wave superconductors. The spatial distribution of the induced s-wave and (Formula presented)-wave components is calculated. The s-wave component has an opposite winding number around the vortex near the (Formula presented)-vortex core and its amplitude has the shape of a four-lobe clover. These are consistent with results based on the Ginzburg-Landau (GL) theory. The amplitude of the (Formula presented) component has the shape of an octofoil. The mixing of the (Formula presented) component cannot be explained by the GL theory, unless nonlocal correction terms are included. © 1996 The American Physical Society.
