Outline of Final Research Achievements

We studied spin fluctuations of iron-based superconductors using neutron scattering technique. Especially, we have examined the magnetic signal, so called spin resonance, which is enhanced strongly in superconducting phase. As results, strong relationship between magnetsim and superconductivity has been demonstrated. The spin resonance disappears in a certain carrier concentration range, which suggests that other interactions rather than magnetism play an essential role in the appearance of superconductivity. Various interactions might cooperate for inducing the superconductivity in iron-based superconductors.
