Abstract (in Japanese) (See Japanese page) 
(in English) Microwave-assisted magnetization switching is a technology, which can reduce the switching field by applying a GHz-band microwave magnetic field. The technology enables to increase magnetic recording density further, by employing media with higher magnetic anisotropy. We have investigated switching behavior under microwave field in nanostructured magnets and granular media. It has been revealed that the switching behavior of nanostructured magnets, which have rather large volume, follows theoretical predictions. Thermal fluctuations have a significant role in granular media because of their small volume. In granular media, their exists interaction between grains. In this paper, we report the effects of inter-grain interaction on microwave assisted switching.
