| Abstract: | 57Fe Mössbauer spectroscopic studies of iron ludwigite Fe3O2BO3 performed between 4 and 450 K allow the discussion of magnetic spin arrangements and the dynamics of electronic configurations of iron. The observed magnetic transitions are related to charge ordering. |
| Keywords: | antiferromagnetism charge order double exchange iron oxyborate M?ssbauer spectroscopy weak ferromagnetism |
