DESCRIPTION:Skyrmions represent topologically stable field configurations 
 with\nparticle-like properties. We use neutron scattering to observe the\n
 spontaneous formation of a two-dimensional lattice of skyrmion lines\, a\n
 type of magnetic vortices\, in transition metal compounds with B20 crystal
 \nstructure. The skyrmion lattice stabilizes at the border between\nparama
 gnetism and long-range helimagnetic order perpendicular to a small\napplie
 d magnetic field - regardless of the direction of the magnetic field\nrela
 tive to the atomic lattice. Our study experimentally establishes\nmagnetic
  materials lacking inversion symmetry as an arena for new forms of\ncrysta
 lline order composed of topologically stable spin states.\n
