A Green's function technique is developed to study the critical behaviour of the s‐d model. The temperature and the magnetic field dependence of the spin magnetization are determined. The critical exponents β and δ are numerically calculated. Applying the scaling laws γ and γ 2 are obtained. The critical exponents are in very good agreement with the experimental data and with other theoretical results.
