| Outline of Final Research Achievements |
The aim of the present study is to synthesize metastable transition metal oxides in a form of thin film and bulk material and to deduce magnetic interactions among the transition metal ions peculiar to the unique crystal and electronic structures different than those of stable phases, so that we can obtain novel compounds and materials relevant to the multiferroics, in which spins are strongly coupled with electric dipoles, and UV-vis magneto-optical devices, for which the interaction between spins and short-wavelength light is very important. We have succeeded in realization of ferromagnetism in Nb-doped EuTiO3 thin films, synthesis of Bi3Fe5O12 thin film and amorphous FeO-SiO2 thin films both of which show extremely large magneto-optical effect, and synthesis of novel lithium niobate-type iron oxides with high magnetic and dielectric transition temperatures.
