Summary: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.
