Magnetization and magnetoreflectivity measurements at Γ point of B.Z. were performed in magnetic field up to 5.5T i) at 4.2K for 0.02 < x < 0.73. An anomalous behavior for high concentration is explained in terms of a second order perturbation calculation, ii) in temperature range 1.8K – 60K for 0.01 < x < 0.30. An important variation of values of ∆E/∣x<S z>∣ with temperature is observed. ∆E is the Zeeman splitting and x<S z> the average spin component. At L point of B.Z. the splitting of Elzstructure compared to splitting at Γ point is very small. A variation of exchange integrals with wavevector has been found necessary to explain the data.
