| Outline of Final Research Achievements |
In order to study a magnetization switching assisted by a spin waves along a thickness direction of an exchange coupled composite (ECC) medium, we developed a micro-MOKE measurement system which enables to spatially resolve the magnetization dynamics. In addition, we succeeded to demonstrate a temporarily resolved observation of nonlinear magnetization dynamics in nonequilibrium state of nano-scaled ferromagnet. From the dependence of a critical switching frequency of an ECC medium on the strength of interlayer exchange coupling, we experimentally confirmed that the spin wave assisted magnetization reversal could be realized even in ultra-thin ECC media with a thickness of 16 nm.
