Outline of Final Research Achievements |
This study was conducted for the purpose of the materials design and structural design of the meultiferroelectric device in order to control of their magnetization by the external electric field. First, thin films of the materials with κ-alumina-type structure were fabricated to investigate ferroelectric and ferrimagnetic properties. Ferroelectricity was confirmed for the all the prepared films. Secondary, ScFeO3 film with YMnO3-type structure, in magnetization is aligned along the perpendicular axis of the film, was fabricated for the fist time. Perpendicular magnetization and ferroelectricity were confirmed at the room temperature. Multiferroic κ-akumina-type this films could be also prepared by the sole-gel and ALD technique.
