Collective electronic excitations in the system of interacting conduction electrons of ferromagnetic metals (Fe, Co, Ni) are investigated. These conduction electrons stem from relatively narrow d-type bands and a suitable model to describe them is the Hubbard model. Treating the Thomas-Fermi screening as a dynamic phenomenon yields oscillations in the electron density. These charge density waves (plasmons) are determined from the poles of the dielectric function ε(q,E) that is approximately evaluated within the random phase approximation RPA. On the other hand, spin wave energies (magnons) are identical to the poles of the transverse susceptibility. Magnetizations m(T,n) , Curie temperatures TC (n), and the temperature dependent exchange splitting ΔEex are calculated within reasonable agreement with experimental results.
