Abstract

The confined effects for magnetostatic (MS) oscillations in normally magnetized thin-film ferrite-disk resonators demonstrate unique properties. The atomic-like character of the experimental MS spectra in such particles shows that the energy of a source of a DC bias magnetic field is absorbing "by portions". In this paper we give the energy spectrum calculations for MS oscillations in a ferrite disk. The oscillating system can be described as a collective motion of quasi-particles - the "light magnons" (lm). Discrete energy levels of "lm" are shown. Effective masses of "lm" are analyzed.
