| Outline of Final Research Achievements |
We investigated the magnetic properties and electrical conduction properties in cylindrical metal-ferromagnetic nanowires. In the research, the following results were obtained. (1) Elucidation of changes in magnetic properties depending on aspect ratio of ferromagnetic nanowires, (2) Elucidation of magnetization reversal behavior in ferromagnetic/nonmagnetic/ferromagnetic nanowires with three-layer structure, (3) Observation of the magnetoresistance effect in single magnetic nanowire and elucidation of its magnetic domain formation.
As other research, we investigated that (4) Elucidation of the correlation between microstructure and magnetic properties in ferromagnetic films composed with oxide magnetic nanoparticles, (5) Analysis of magnetization structures and elucidation of spin dynamics by using micromagnetic simulations. These results could clarify the magnetic properties and spin dynamics in antiferromagnet nanowires and magnetized synthetic antiferromagnetic coupling structure.
