The Impact

We have considered the impact of the nontrivial superconducting order parameter on the magnetic susceptibility within the multiorbital model for the iron-based materials. The formation of the spin-resonance peak is demonstrated and its connection to the experimental data on the inelastic neutron scattering is discussed.
