| Research Abstract |
Unusually high valent cations are known have exotic electronic structure and cause interesting physical properties. In this project, charge disproportionation and charge transfer phenomena in A-site-ordered perovskites CaCu3Fe4O12 and LaCu3Fe4O12 containing unusually high valent cations were investigated and the mechanisms of these unusual phenomena were explained systematically. Such understandings will enable to design and develop novel functional materials.
