Ferromagnetic phase transition of the film and surface is studied by the met-hod of Green’s function based upon Heisenberg model with the surface magneticanisotropy.It is proved that the order parameter (spontaneous magnetization)cha-nges with the position in the ferromagnetic film which loses translational invar-iance in one direction.The expressions of Curie temperature and spontaneous mag-netization of each atomic layer in the film have been derived.One expect that theextraordinary phenomena will exist in very thin ferromagnetic film

for instance

as the thickness of film is decreased

Gurie temperature raises

etc.
