• On the basis of the sf exchange model and by the method of Green functions, a many-body theoretical formulation is given to the problem of exchange enhancement of electronic specific heat in a ferromagnetic metal. By introducing the spin wave description of localized spins, the sf Hamiltonian is reduced to a form similar to the coupled electron-phonon system, and Dyson equations are solved by the Migdal approximation. For the same reason as is known in the electron-phonon case, we expect, independently of the detail of the model, the exchange enhancement of electronic specific heat may amount to hundred percents.
