The magnetic field effect on the properties of magnon population in the super-lattice Co/Ag is investigated within the framework of spin waves theory. The corresponding Heisenberg Hamiltonian is diagonalized using the Green functions method. Excitation spectrum and magnetization per spin are calculated. The compared measured and calculated magnetizations are in good agreement allowing us to deduce exchange integrals J whose values are in coherence with what is found usually for this type of super lattices made of 3d metal transition. A study of the combined effect of dipolar interaction and surface anisotropy is also reported
