Abstract

A magnetic structure near the surface of ferromagnetic superconductors is theoretically studied in the temperature range of the coexistence of superconductivity and magnetism. The screening effect of the exchange interaction due to the persistent current is weakened near the surface and a spontaneous magnetization bound near the surface appears at a temperature slightly higher than the phase transition temperature of the bulk periodic phase, Tp. Below Tp, th periodic magnetic structure is modified near the surface so as that the ferromagnetic character is emphasized.
