An overview of studies is presented on 3d electron superconductors NaxCoO2·yH2O and Fe-based systems discovered after high-Tc Cu oxides. We present how the neutron inelastic scattering contributed to clarify whether the magnetic mechanism is primarily important for the occurrence of the superconductivity. We also present results of the studies on dynamical properties of their lattice systems to search alternative candidate of the superconducting pairing mechanism.

Key words: Neutron inelastic scattering; Fe-based supeconductors; Hydrated NaxCoO2; Phonons; Magnetic excitations
