| Outline of Final Research Achievements |
We found an anomalous behavior of localized magnetic moments in itinerant electronic ferromagnets, and have tried to clarify the mechanism of it. As results, we found that localized magnetic moments couple with internal field from ferromagnetic sublattice, leading to the anomalous temperature and magnetic field dependences of them. Such a coupling can be seen as the coupling of ferromagnetic moments with localized magnetic moments, and this viewpoint indicates a possibility to control ferromagnetic moments through controlling localized magnetic moments which couple with ferromagnetic moments. We found that the ferromagnetic-antiferromagnetic transition observed in layered ferromagnetic compounds can be understood by this mechanism.
