摘要: Properties of a type II triplet superconductor with equal spin pairing are investigated using the phenomenological Ginzburg–Landau approach. It is shown that there exist two kinds fluxons: vortices and magnetic skyrmions. Vector nature order parameter allows direct coupling effective condensate to field. This coupling, which reminiscent Zeeman interaction in form, significantly modifies structure an isolated vortex, as compared usual Abrikosov changes energetics vortex lattice. If sufficiently strong, then magnetization becomes positive at high fields. Formation spontaneous state also possible.
