| Outline of Final Research Achievements |
The properties of the magnetic materials are greatly affected by the magnetic moment with electronic spin. Therefore, understanding of the exchange interaction between the spin is important essentially to design the nanomagnetic body as a new function. In this study, we use the magnetic exchange force microscopy with the ferromagnetic resonance to measure the exchange interaction of a nanomagnetic body built on the insulator surface with the atomic-scale and elucidate it how to influence exchange interaction by atomicity and a dimension, structure of nanostructure. As a result, first, we realized magnetism exchange force microscopy with the highest resolution and highest sensitivity. Second, we developed a method of deriving an exchange force from the modulation frequency included in the frequency shift of the cantilever.
