From: Intertwined electronic and magnetic structure of the van-der-Waals antiferromagnet Fe2P2S6
a Sketch of the local spin arrangement and possible intersite transitions parallel or perpendicular to the spin chain. Spin up and down is highlighted by red and blue. b Schematical Fe 3d DOS. c Joint density of states following from (b) respecting available phase space. d Same as (c) under consideration of exchange energy. e ϵ2 calculated by DFT + U.
