Study on the magnetization dynamics of Ni-Fe dot arrays estimated by the CPW-FMR measurement method

Nanomagnets are much attractive as promising materials for practical applications, including nonvolatile magnetic random access memories (MRAMs), magnetic storage media, magnetic logic devices and so on. In addition, they have been studied intensively from a micro-magnetism point of view, e.g., the magnetization process of nanomagnets, their magnetic states, their magnetization dynamics and so on. In particular, understanding the magnetization dynamics of nanomagnets is very important from both fundamental and applied points of view.
