| Outline of Final Research Achievements |
Mossbauer spectroscopy is a powerful technique to investigate the local electronic and magnetic structures around Fe sites. We have developed novel techniques adding the electric-field induced Mossbauer spectroscopy. We prepared the sample holder for applying the electric field during Mossbauer spectroscopy with conversion electron Mossbauer spectroscopy (CEMS). We obtained the results in the temperature dependent Debye-Waller factors in Mossbauer spectra in novel magnetic complexes, which is comparable to the spectra in X-ray absorption. This research opens up the new basic concept adding the physical parameters of electric field into Mossbauer spectroscopy.
