Аннотация:
The metamagnetic (or spin-flop) transition which is experimentally observed in certain antiferromagnetic superconductors results in the formation of magnetic domain structure if the demagnetization factor of the sample is nonzero. It is demonstrated that such structure leads to the modulation of vortex lattice density which is maximal in the domains of spin-flop phase. The structure of a vortex with a ferrimagnetic domain near its core is also investigated. The results of calculations show that under appropriate conditions the interplay between superconductivity and metamagnetism makes the formation of peculiar two-quanta vortices energetically favourable.
