We discuss the physics of the vortex state in a {ital d}-wave superconductor, using the phenomenological Ginzburg-Landau theory, where many unusual phenomena arise from the small admixture of the {ital s}-wave component induced by spatial variations in the dominant {ital d} wave. Properties of an isolated vortex and of the Abrikosov vortex lattice are studied by means of analytic and numerical methods. An isolated vortex has a considerable structure, with four {open_quote}{open_quote}extra{close_quote}{close_quote} nodes in the {ital s}-wave order parameter symmerically placed around the core and an amplitude forming a four-lobe profile decaying as 1/{ital r}{sup 2} at large distances. The supercurrent and magnetic-field distributions are also calculated. The Abrikosov lattice is in general oblique with the precise shape determined by the magnetic field and {ital s}-{ital d} mixing parameter {epsilon}{sub {ital v}}. The magnetic-field distribution in the Abrikosov state has two nonequivalent saddle points resulting in the prediction of a double peak line shape in {mu}SR and NMR experiments as a test of a {ital d}-wave symmetry. Detailed comparison is made with existing experimental data and experiments are proposed to test for the predicted effects. {copyright} {ital 1996 The American Physical Society.}
