- Description
- A three-orbital itinerant-electron model involving dxz, dyz, and dxy Fe 3d orbital is proposed for iron pnictides towards understanding the (ð, 0) ordered magnetism and magnetic excitations in these materials. It is shown that this model simultaneously reproduces several experimentally observed features such as circular hole and elliptical electron pockets in the electronic Fermi surface structure, quantitatively correct spin wave dispersion, as well as the ferro-orbital order between the dxz and dyz orbital. .
