Abstract
The rich order parameter of Spin Density Waves allows for an unusual object of a complex topological nature: "Chimeras" composed by a half - integer d islocation combined with a semi - vortex of the staggered magnetization. Th ey become energetically favorable due to enhanced Coulomb interactions. The ir generation changes the NBN frequency.
