Using a Ginsburg-Landau free-energy functional, we study the
H-T phase diagram of a weak magnetic superconductor, where the
magnetization from the magnetic component is marginal in
supporting a spontaneous vortex phase. In particular, the
competition between the spiral state and spontaneous vortex phase
is analysed. Our theory is applied to understand the magnetic
properties of .
