Outline of Final Research Achievements

In a single crystal, physical features such as a configuration of atoms, an electronic state, and a magnetism in an unit cell generally bring a passway to understand a mechanism of functionality. However, there are some cases, where a crystallinity and a domain size greatly reflect on physical properties in a macro scale. In this report, studies on a domain structure in a typical material, which play an important role in functionality, are summarized, as well as physical properties in a local site.
