Influence of Lattice Symmetry on the Magnonic Spectra in Magnetic Nanodot Lattice

摘要

The magnetostatically coupled ordered lattices of nanomagnets show the long wavelength collective dynamics where the dynamics of the constituent nanomagnets maintains constant amplitude and phase relationships. The long wavelength collective dynamics in the form of Bloch waves defined in the first Brillouin zones of an artificial lattice, can also be manipulated by tailoring the lattice to form two-dimensional magnonic crystals.
