A small FMR ferrite disk strongly perturbs the cavity field. Graphical representation of the Poynting vector shows that due to the vortex structure the absorption cross-section of a ferrite particle can be much bigger than its geometrical cross-section. Spectral properties of magnetic oscillations in a ferrite disk show unique vortex structures for MS-wave functions.
