Outline of Final Research Achievements

In order to propose a method for design of ferroelectric materials, we synthesized some novel ferroelectric-related materials as case studies and tried to crystallographically explain the dielectric and ferroelectric properties. Especially, by measuring the dielectric permittivity of a novel silicate ferroelectric compound and mixed-anion dielectrics in a wide frequency range, it was possible to comprehensively understand the dielectric properties from the viewpoint of electronic structureand lattice vibration, etc. This research presents a research process that quantitatively connects the relationship among the crystal structure, lattice vibration, and dielectric properties, and therefore the process is thought to lead to a design method for the next generation ferroelectric materials.
