Ferromagnetic Resonance and Effect of Supercurrent on the Magnetization Dynamics in S/F/S Junctions under Circularly Polarized Magnetic Field

The coupling between the Josephson phase and magnetization in Superconductor/Ferromagnet/Superconductor (S/F/S) junctions plays an important role in the dynamics of this system. In the presence of this coupling, we demonstrate the manifestation of the ferromagnetic resonance (FMR) in the frequency dependence of the magnetization and critical current of S/F/S Josephson junction under circularly polarized magnetic field. Furthermore, we compare the simulation results in both the nonlinearized and the linearized models. The ferromagnetic resonance linewidth and the resonance frequency are strongly affected by the ratio of the Josephson and magnetic energies.
