Comparison of experimental data on the spin resonance frequency and gap magnitudes in Fe-based superconductors

Comparison of experimental data on the spin resonance frequency and gap magnitudes in Fe-based superconductors

Here we review experimental data on the peak in inelastic neutron scattering (INS) and superconducting gaps extracted from various experimental techniques. Comparison of energy scales gives the confidence that the observed peak in INS for most materials is the true spin resonance.
