Abstract
Dynamic susceptibility and spin waves in thin ferromagnetic films of transition metals are investigated numerically within the framework of the multiband model for various values of the surface one-electron potential. The tight-binding approach is used. Influence of the potential shifting on the one-electron properties and spin waves is profoundly discussed. Results, consistent with those obtained in the one-band model, show that acoustic surface modes appear for cases of increasing of the surface potential, which lead to surface magnetization enhancement.
