Magnetism and its microscopic origin in iron-based high-temperature superconductors

P Dai, J Hu, E Dagotto - Nature Physics, 2012 - nature.com
High-temperature superconductivity in the iron-based materials emerges from, or sometimes
coexists with, their metallic or insulating parent compound states. This is surprising, as these …
