Title: Quasiclassical Theory of C4-Symmetric Magnetic Order in Disordered Multiband Metals

Abstract

Recent experimental studies performed in the normal state of iron-based superconductors have discovered the existence of the C₄-symmetric (tetragonal) itinerant magnetic state. This state can be described as a spin density wave with two distinct magnetic vectors ${\vec{Q}}_{1}$ and ${\vec{Q}}_{2}$ . Given an itinerant nature of magnetism in iron-pnictides, we develop a quasiclassical theory of tetragonal magnetic order in disordered three-band metal with anisotropic band structure. Within our model we find that the C₄-symmetric magnetism competes with the C₂-symmetric state with a single $\vec{Q}$ magnetic structure vector. Our main results is that disorder promotes tetragonal magnetic state which is in agreement with earlier theoretical studies.
