The effects of RF radiation on longitudinal and transverserelaxation rates are negligible, while the RF radiation depresses cross-relaxation rate to some extent.
A mathematical formula of the relation between longitudinal relaxation or transverserelaxation and the flip Angle of magnetization vector was deduced and its programme was designed.

The transverse migration of the atoms is the main route of film relaxation. The competition between atomic implantation and migration determines the growth mode and final structures of the film.
