| Research Abstract |
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.
