Abstract:
The coupling between the superconducting current and magnetic moment in the SFS Josephson junction plays an important role in the dynamics of this system. we study a Josephson junction coupled to a nanomagnet with an easy-axis magnetic anisotropy. We demonstrate the manifestation of ferromagnetic resonance in the maximum amplitude of the magnetic moment components. In addition to this, a reorientation of easy axis occurs by changing the model parameters. The effect of external radiation on the reorientation point is demonstrated.
