Maximum dc Josephson current in two magnetic superconductors joined together by a non-superconducting junction is estimated in the temperature region between the superconducting-and magnetic-phase transition temperatures. The magnetic field induced by the persistent current crossing the junction and the persistent current along the junction is quantitized along with the polarization of the local spins of the rare-earth ions. On the other hand, the fluctuations of the local spins weaken the BCS coupling constant. As a result, the current depends strongly on temperature and decreases near the magnetic-phase-transition temperature.
