Fabrication of the functional fusion oxide thin films which had a number of ferroic properties was carried out by the chemical solution deposition process that composition control was facile, and optimization of the doping of the functional element (Mn) to obtain desired properties was successfully achieved. In addition, for the elucidation of the properties improvement mechanism by the doping of the functional element, the valence state of the doped element and relations based on the defect chemistry between electrical and magnetic properties were clarified. Furthermore, visualization of the interaction between ferroelectric and magnetic domains was achieved.

采用易于成分控制的化学溶液沉积工艺制备了具有多种铁性的功能性熔融氧化物薄膜，并成功实现了功能元素（Mn）掺杂的优化以获得所需的性能。此外，为了阐明通过功能元素的掺杂来改善性能的机制，阐明了掺杂元素的价态以及基于电学性能和磁学性能之间的缺陷化学的关系。此外，还实现了铁电域和磁域之间相互作用的可视化。
