We study noncoplanar magnetic ordering in frustrated itinerant magnets. For afamily of Kondo square lattice models with classical local moments, we findthat a double-$Q$ noncoplanar vortex crystal has lower energy than thesingle-$Q$ helical order expected from the Ruderman-Kittel-Kasuya-Yosidainteraction whenever the lattice symmetry dictates four global maxima in thebare magnetic susceptibility. By expanding in the small Kondo exchange and thedegree of noncoplanarity, we demonstrate that this noncoplanar state arisesfrom a Fermi surface instability, and it is generic for a wide range ofelectron filling fractions whenever the two ordering wave vectors connectindependent sections of the Fermi surface.
