Collective mode excitation assist for magnetization reversal
The large arrays of magnetic dots are the basis of magnonic crystals and bit patterned media. Resonance behaviors of densely packed magnetic arrays have been a subject of recent intensified research for their applications in microwave technology or signal transfer. Structural or magnetization non-uniformities in magnonic crystals lead to the appearance of defect modes, resulting in the modification of the magnon band-structure. It has been demonstrated experimentally that the state of a vortex matrix, is selectively formed under different frequencies of microwave excitation.
