| Outline of Final Research Achievements |
We developed multi-layered nanocomposite thick film-magnets composed of 10-nm-thick Sm-Co and Fe layers stacked alternately approximately 1000 layers by the pulsed laser deposition method. The magnets were isotropic and (BH)max value of 100 kJ/m3 was obtained, when the substrates were not heated. Thin buffer layers such as Ta and Cu between Sm-Co and Fe layers improved their magnetic properties significantly. Furthermore, the application of the two-step annealing method enabled us to obtain anisotropic multi-layered thick film-magnets whose easy axis of magnetization lies in the film-plane.
