Abstract: THe in Inwhayer exchange Paramters near the surface of a ferromagnetic film have been calcuated;and they have been extended to the case of the semi-infinite sample.The results exhibit that the exchange interaction near the surfare is greater than that of the bulk.This confirms theoretically the assumption made by Mills.

Key words: surface, interlayer exchange integral, thin ferromagnetic film
