Abstract (in Japanese) (See Japanese page) 
(in English) Microwave assisted magnetic reversal behavior for single exchange coupled nano-pillar was analyzed considering exchange coupled composite media using micromagnetic simulator. In the case that the thickness of the soft magnetic layer is substantially thinner than exchange length, the magnetization behaviors for soft and hard layers are almost uniform because of the strong exchange coupling between hard magnetic layer and thin soft magnetic layer. On the other hand, magnetization behaviors dominated by the soft and the hard magnetic layers were found at low and high frequency region for the ECC pillar when the thickness of soft magnetic layer is close to exchange length. Microwave frequency and microwave field strength required for magnetization reversal were also found to be lower and smaller than those for hard magnetic layer only.
