Long range dipole-dipole correlation in a ferromagnetic sample can be treated in terms of
collective excitations of the system as a whole. Ferrite samples with linear dimensions
smaller than the dephasing length, but still much larger than the exchange-interaction
scales, are mesoscopic structures. Recently, it was shown that mesoscopic quasi-2D ferrite
disks, distinguishing by multiresonance magneto-dipolar-mode (MDM) spectra, demonstrate
unique properties of artificial atomic structures: energy eigenstates, eigen power-flow …
