| Outline of Final Research Achievements |
In this research, we prepared the nano-composite thin films with new multi-functional properties, composed of magnetic metal nano-granule dispersed in the dielectric matrix. New magneto-dielectric effect, namely "Tunneling Magneto-Dielectric (TMD) effect" was discovered in nano-composite film composed of dielectric ceramics (MgF2) and magnetic metal nano-granule (FeCo).Optically transparent ferromagnetic films with tunable transmittance, namely "Tunneling Magneto-Optic (TMO) effect" material was developed in nano-composite film composed of dielectric ceramics (AlF3) and magnetic metal nano-granule (FeCo).
