Spin wave behavior and resonance frequency of graphene-like magnetic film with six sublattices

In this study, the Heisenberg model is constructed, and the spin wave spectra of graphene-like magnetic film with six sublattices were calculated using spin wave theory and the Green's function method. The effects of exchange coupling, anisotropy, and spin quantum number on the energy gap and resonance frequency of the system were investigated. The present results show the method to adjust the energy gap and resonance frequency.
