Ni-Fe thin films are deposited on the corning glass substrate by means of RF magnetron sputtering system In order to investigate the dependence of the prorerties of Ni-Fe thin films on the film thickness, ferromagnetic resonance spectrum has been examined. The effective magnetization Meff is constant for all samples, while the exchange stiffness constant A increases with the film thickness. A tendency that spectroscopic splitting factor g increases with the sample thickness, we expect that the increase of the contribution of the orbital motion to the magnetic moment as a reason for it.
