Our fundamental study showed the potential of novel magnetic memory system by using the hybridized properties of magnetic and dielectric materials. It was focused on the interfacial mechanical behavior between the magnetic materials and the dielectric ones. That is ferrite-based, and the rare-earth and transition compounds-based magnetstrictive materials and this is the piezoelectric materials of LiNbO3 and polymer. The mechanical properties of material interface were simulated by the finite element method (FEM), prior to the experimental study, which was related to the hybrid material design and synthesize, and the interaction of material with visible light and synchrotron x-ray.We examined the synthesis of magnetic inorganic material by sol-gel method and of the compound and the polymer films by electrochemical method, and the construction of electrochemical, electro-optical, and magneto-optical measurement systems. The experimental data obtained by these techniques provided us the fundamental aspect for our anticipated material functions.
