| Outline of Final Research Achievements |
In order to show effectiveness of a tri-axial magnetic alignment technique as a material production process, a manipulation technique of tri-axial magnetic anisotropies and magnetization axes in layered functional oxide materials with orthorhombic crystal structure, such as high-Tc superconductors and thermoelectric materials could be found. Modulation structure and twin microstructure decrease the magnetic anisotropy in a grain level, whereas doping of heavy-rare-earth ions such as Ho, Dy, and Er and crystallochemical control in a molecular level can improve the magnetic anisotropy in the grain level. This research project can find a crystallochemical strategy for the control of tri-axial magnetic anisotropies of the layered oxide materials in the grain level.
