Modeling of Forced Oscillations of Magnetization in a System of Three Ferromagnetic Nanodisks

Micromagnetic modeling of ferromagnetic resonance (FMR) is carried out in a system comprising a cylindrical stack consisting of three ferromagnetic nanodisks, in which a helicoidal distribution of magnetic moments is realized due to magnetostatic interaction in the equilibrium state. Specificities of the rearrangement of the FMR spectrum and the spatial structure of the resonant oscillations of such a system in an external magnetic field are studied.
