| Outline of Final Research Achievements |
The effective magneto－optical properties of novel nonanuclear Tb(III) clusters with paramagnetic Tb(III) ions were studied. The geometrical structures of these nonanuclear Tb(III) clusters were characterized using X-ray single-crystal analysis and shape-measure calculation. Optical Faraday rotation was observed in PMMA thin films containing nonanuclear Tb(III) clusters in the visible region. The Verdet constant per Tb(III) ion of the Tb clusters is 150 times larger than that of general Tb(III) oxide glass. To understand their large Faraday rotation,electron paramagnetic resonance measurements were carried out. In this study, the magneto－optical relation to the coordination geometry of Tb ions was demonstrated for the first time.
