| Outline of Final Research Achievements |
Magnetic properties of layered magnets are highly depending on the types of intercalated molecules. In this research, we employed dithiooxalato bridged iron mixed-valence complexes (dto complexes) or cobalt layered hydroxides (Co-LHs) as a layered ferromagnet. Combination between these complexes and functional counter ions is promised candidate to realize a functional materials with cross-correlated spin system. Firstly, we prepared the cations with rotatory functional groups to introduce a polarization between the magnetic layers of dto complex. From the result of this experiment, we succeeded to obtain a material with the coexistence of the charge transfer in the magnetic layers and the polarization of the cation layers. On the other hand, we introduced some photoisomerization molecule, that is, sulfonated diarylethene (DAE) derivatives, as intercalants to Co-LH. The result indicates that the correlation between the state of DAE and the ferromagnetic behavior of Co-LH is very small.
