Antiferromagnetic order and spin dynamics in iron-based superconductors
Antiferromagnetic order and spin dynamics in iron-based superconductors
High-transition temperature (high-$T_c$) superconductivity in the iron pnictides/chalcogenides emerges from the suppression of the static antiferromagnetic order in their parent compounds, similar to copper oxides superconductors. This raises a fundamental question concerning the role of magnetism in the superconductivity of these materials. Neutron scattering, a powerful probe to study the …
