| Research Abstract |
Synthesis of metal-ceramics type nano-hetero multiphase materials and their properties have been investigated, based on the nano-granular magnetic films which we found. The films with nano-hetero multiphase structure have been self-assembled by material-designing considered the heat of formation of constructional materials. They show excellent functional properties, e.g., Co-Ti-O films have the MR ratio of 11% (at RT & 10 kOe), and Co-Nb-O films show both magnetic and dielectric properties simultaneously.
