摘要
The characteristic of microwave assisted switching for an isolated grain was investigated using the Landau-Lifshitz-Gilbert simulation. It was found that anticlockwise and clockwise polarized fields assist magnetization to switch and to reswitch, respectively. Using larger linear polarized field, sufficient switching is not obtained. It was confirmed the magnetic resonance effect on the reduction in the switching field. It was also found that a large assist effect and a narrowing transition effect were achieved in exchange coupled subgrains. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3075850]
