✦ Synopsis

We present a calculation of the coexistence of superconductivity and ferromagnetism in the s-d model for the case when the exchange interaction between the ferromagnetically aligned d electrons and the conduction electrons is weak and the effects can be considered of the first order. The equations for the order parameter and the polarization of the conduction electrons have been derived using a Green's function method for two limiting cases : (a) a f-function density of states and (b) a constant density of states.
