| Outline of Final Research Achievements |
The purpose of this work is to develop a theory of magnetization dynamics, related to microwave assisted magnetization reversal (MAMR), based on nonlinear science. I have theoretically proposed a new device design of spin-torque oscillators (STOs) applicable to MAMR. I have also proposed new mechanisms of synchronization phenomena excited in STOs by using theory of spin transport in nanostructured ferromagnets. These results contribute to the development of physics, in particular in the field of magnetism, spintronics, and nonlinear science. In addition, these results will be useful for research on next-generation high-density magnetic recording.
