Complete topological classification of solutions in SO(3) symmetricGinzburg-Landau free energy has been performed and a new class of solutions inweak external magnetic field carrying two units of magnetic flux has beenidentified. These solutions, magnetic skyrmions, do not have singular core likeAbrikosov vortices and at low magnetic field become lighter for strongly typeII superconductors. As a consequence, the lower critical magnetic field Hc1 isreduced by a factor of log(kappa). Magnetic skyrmions repel each other as 1/rat distances much larger then magnetic penetration depth forming relativelyrobust triangular lattice. Magnetic induction near Hc1 increases gradually as(H-Hc1)^2. This agrees very well with experiments on heavy fermionsuperconductor UPt3. Newly discovered Ru based compounds Sr2RuO4 andSr2YRu(1-x)Cu(x)O6 are other possible candidates to possess skyrmion lattices.Deviations from exact SO(3) symmetry are also studied.Comment: 23 pages, 10 eps figure
