| Outline of Final Research Achievements |
In this research project, we performed the neutron scattering study on the oxygen molecule magnets in order to investigate the novel phenomena caused by the strong correlations between the lattice and spins in these magnets. In fact, we carried out the polarized neutron scattering experiments on the deuterated porous complex CPL-1 to understand the origin of the excitation which has characteristic temperature dependence. We found that there is no contribution from the nuclear-magnetic interference term, and that magnetic contribution only exists at low temperatures for this excitation.

| Academic Significance and Societal Importance of the Research Achievements |
細孔性錯体は気体吸蔵の観点から主に無機化学の分野で精力的に研究されているが、吸着酸素の構造や酸素分子のもつ磁性に着目した研究は少ない。本研究によって、吸着した酸素のダイナミクスを調べるのに重水素化錯体を用いた中性子散乱を行う手法が有効であることが分かった。これによって、今後酸素分子磁性体において発見されうる新奇な磁性を同様の手法によって調べ、その起源を明らかにすることができると期待される。また、さらに中性子散乱によって吸着された酸素分子のダイナミクスへの理解がさらに進めば、錯体の気体吸蔵特性の向上にも寄与する可能性がある。
