Outline of Final Research Achievements |
Electronic ferroelectric, RFe2O4 (R: rare earth) is a candidate of ultra-high-speed and energy saving device, due to its multiferroic property and magnetoelectric effect. Therefore the control of the charge order is demanding task. In this study, YbFe2O4 film was fabricated to control the charge order. I succeeded in growing high-oriented YbFe2O4 film. The exceptionally reduced atmosphere should be effective to control the charge order, although it remains an issue. In order to expand the application possibility, also the bulk property was studied. It was clarified that the fermi level is controllable by the modulation of the charge order. This phenomenon is novel and can be applied to cheap and universal semiconductor.
