Construction of Fine-structured Interface Between Dielectric and Magnetic Materials, and Creation of Novel Intelligence Memory Function

我们的基础研究利用磁性材料和介电材料的混合特性，展示了新型磁存储系统的潜力。重点研究了磁性材料与介电材料之间的界面力学行为。即以铁氧体为主，以稀土和过渡化合物为主的磁致伸缩材料，这是由LiNbO_3和聚合物组成的压电材料。在实验研究之前，利用有限元方法对材料界面的力学性能进行了模拟，这涉及到杂化材料的设计和合成，以及材料与可见光和同步辐射X射线的相互作用。我们考察了溶胶-凝胶法合成磁性无机材料，电化学方法合成化合物和聚合物薄膜，以及电化学、电光和磁光测量系统的构建。通过这些技术获得的实验数据为我们预期的物质功能提供了基本方面。

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.
