We have considered vortices in p-wave superconductors with a nonvanishing order parameter in the vortex core for the arbitrary ratio κ = λ/ξ (here λ and ξ are the magnetic length and the coherence length, correspondently). Vector vortices are characterized by an orientation in the order-parameter space, however, spatial profile of both the order parameter and magnetic field of the vortex demonstrate an essential difference of the vortex structure for different κ parameters and from those calculated for the vortex in liquid 3He. We calculate lower critical field Hc1 and find that critical (Formula presented) is independent of the detailed form of interactions. Strong asymmetry of some of the components of the order parameter disappears when κ approaches κc. The vortex lattice in the multicomponent superconductor resembles a spin system in which the orientation in the order-parameter space plays the role of “spin.” Interactions between vortices lead to long-range order. An effective theory for this system is proposed.
