Abstract
In the paper, the results of the study of ferromagnetic resonance in a φ0 junction, in which the phase difference couples directly to the magnetic moment of the barrier, are presented. We have calculated current–voltage characteristics, average superconducting current dependences on the bias current and voltage, and dependences of the maximum amplitude of the magnetization components on the applied voltage at different parameters of spin–orbit coupling. We show the emergence of a constant component of a superconducting current as the effect of coupling between the magnetization and the spin–orbit interaction, and we clarify the role of the coupling in the transformations of current-voltage characteristics occurring in the resonance region. The results presented can be used to develop new resonance techniques for determining the spin–orbit coupling parameter in noncentrosymmetric materials.
