| Outline of Final Research Achievements |
The first purpose of this scientific research is that of the creation of new type nano-dots using the thin film materials FeCoSm with being spin-operated at over 30 GHz-1 THz. In addition, the second purpose is that of clarifying quantum magnetic interactions between nano-dots as a solitons with spin dynamics over 30 GH-1 THz, being induced by supergiant uniaxial magnetic anisotropy.
We have succeeded in the creation of tens of new type nano-dots by means of new specially developed sputter method. On the other hand, spin-operation at over 30 GHz-1 THz co-with supergiant uniaxial magnetic anisotropy confirmed on the way of measuring for details.
