Abstract A microscopic theory of superconductors containing a magnetically polarizable medium is given. By taking into account the Zeeman effect, we derive the crossover behavior from a second- to a first-order phase transition, the magnetization curve in the high-field region, and the magnetization jump at the first-order phase transition temperature. The theory gives a qualitative account of the magnetic behavior, including the remarkable convex curvature of the magnetization curves, observed in the ferromagnetic superconductor ErRh4B4 with applied external field parallel to the magnetic easy axis.
