WebFeb 11, 2013 · Spin states with long-range incommensurate magnetic order may be stabilized by itinerant electrons through two distinct mechanisms. If the Fermi surface has well-nested regions, the itinerant electrons themselves typically become unstable toward the formation of a spin-density wave (SDW) ().A prominent example of this class of materials … WebLove the spatula and spin rest ability.
