  Topological analysis of nearly SO(3)_{spin} symmetric Ginzburg--Landau
theory, proposed for UPt$_{3}$ by Machida et al, shows that there exists a new
class of solutions carrying two units of magnetic flux: the magnetic skyrmion.
These solutions do not have singular core like Abrikosov vortices and at low
magnetic fields they become lighter for strongly type II superconductors.
Magnetic skyrmions repel each other as $1/r$ at distances much larger then the
magnetic penetration depth $\lambda$, forming a relatively robust triangular
lattice. The magnetic induction near $H_{c1}$ is found to increase as
$(H-H_{c1})^{2}$. This behavior agrees well with experiments.
