## Abstract The influence of the s‐d interaction on the ferromagnet with __S__ = 1/2 with nearest‐neighbour exchange interaction has been considered using the double‐time Green's functions. The equations of motion have been obtained for two kinds of Green's functions __G__(−) and __G__(+), which ar
