N2 - An effective exchange interaction between rare-earth magnetic moments near the surface of ferromagnetic superconductors is calculated under various surface boundary conditions both for the persistent current and the original exchange coupling in the normal state. In the bulk system, the persistent current screens the exchange interaction through the electromagnetic interaction, but the screening effect is weakened in the vicinity of the surface. The behavior of the penetrated magnetic field is calculated by using the obtained effective exchange interaction. Some discussions are given on the comparison between the present calculation and our previous calculation made by the boson transformation method.
