| Outline of Final Research Achievements |
In this study, Fe- and Te- Mossbauer spectroscopies were applied to a Fe-based superconductor, FeTe1-xSex. One of the main results was that we have observed internal magnetic field not only for Fe but also for Te when it has the antiferromagnetic order. This fact implies that the magnetic order in Fe affects the electronic state of Te through hybridization between Fe and Te orbitals.
