Oral presentation

Inelastic neutron scattering study of iron-based superconductors FeSe$$_{0.5}$$Te$$_{0.5}$$ and FeSe; Nematic effect of magnetic scattering spectra

Iron-based superconductors FeSe$$_{0.5}$$Te$$_{0.5}$$ and FeSe have been studied by inelastic neutron scattering measurement. In contrast of FeSe, FeSe$$_{0.5}$$Te$$_{0.5}$$ exhibits temperature dependent incommensurability in magnetic spectrum with no clear structural transition. We find a jump in the incommensurability at about 70 K.

Nematic effect on spin excitations of FeSe$$_{0.5}$$Te$$_{0.5}$$5 and FeSe

Iron-based superconductors FeSe$$_{0.5}$$Te$$_{0.5}$$ and FeSe have been studied by inelastic neutron scattering measurement. Although FeSe$$_{0.5}$$Te$$_{0.5}$$ does not exhibit any clear structural transition, the incommensurate magnetic excitation shows a jump at about 70 K in the incommensurability. It may suggest that the degeneracy of d$$_{zx}$$ and d$$_{yz}$$ orbitals in FeSe$$_{0.5}$$Te$$_{0.5}$$ is lifted in this temperature range. It can be due to the nematic effect even in FeSe$$_{0.5}$$Te$$_{0.5}$$.

Inelastic neutron scattering study of $$beta$$-FeSe

Iron-based superconductor $$beta$$-FeSe has not been studied in the high energy region by inelastic neutron scattering measurement. We have studied it with the single crystals grown by chemical vapor transport method. As a result, spin-wave like dispersion, which can be fitted by two types of anisotropic exchange interactions, is observed up to 200 meV.
