Itinerant Half-Metal Spin-Density-Wave State on the Hexagonal Lattice

We consider electrons on a honeycomb or triangular lattice doped to the saddle point of the band structure. We assume the system parameters are such that spin density wave (SDW) order emerges below a temperature T[subscript N] and investigate the nature of the SDW phase. We argue that at T≤T[subscri...
