Theory of Two-Magnon Raman Scattering in Iron Pnictides and Chalcogenides
Theory of Two-Magnon Raman Scattering in Iron Pnictides and Chalcogenides
Although the parent iron-based pnictides and chalcogenides are itinerant antiferromagnets, the use of local moment picture to understand their magnetic properties is still widespread. We study magnetic Raman scattering from a local moment perspective for various quantum spin models proposed for this new class of superconductors. These models vary greatly …
