Abstract
Using a Ginsburg-Landau free-energy functional, we study the H-T phase diag ram of a weak magnetic superconductor, where the magnetization from the mag netic component is marginal in supporting a spontaneous vortex phase. In pa rticular, the competition between the spiral state and spontaneous vortex p hase is analysed. Our theory is applied to understand the magnetic properti es of ErNi2B2C.
