Using Ginzburg-Landau theory, we consider the effect of a magnetic field on the anisotropic (/sup 3/P/sub 2/) neutron superfluid. In a strong magnetic field, the pairing state has an angle-dependent energy gap with a node along the field direction. Methods of homotopy theory are used to determine the topologically stable line defects allowed by the /sup 3/P/sub 2/ order parameters. Our free-energy analysis of line vortices gives a qualitatively different structure to the single vortex, outside of the core region, from that obtained by other authors.
