Abstract
An integrodifferential equation describing the dynamics of the phase difference with spatial and temporal nonlocality is derived for a Josephson junction in a thin film of magnetic superconductor. It is shown that the magnetic subsystem renormalizes the spectrum of small-amplitude electromagnetic excitations and leads to their damping.
