| Outline of Final Research Achievements |
Developments of electromagnetic devices require multi-functional materials, such as magnetic-dielectric films, and multiferroic materials. The nanocomposite films consist of magnetic nano-sized metal particles and an insulator phase. These films have significant practical advantage of easy fabrication and have been applied in magnetic sensors. They possess enhanced properties such as the high dielectric constant, magneto-dielectric effects , and magneto-optical effects at room temperature.However, it is usually difficult. Because conventional deposition systems keep the metal and the ceramic deposition in the same atmosphere, which easily induce the intermixing at interface. In this research, I have developed the newly Differential pressure sputtering (DPS) method, and successfully realize controlling the interface of the Oxide-Metal nano-composite films.
