Abstract Ferromagnetic resonance (FMR) and torsion magnetometry were carried out on 60 Ni/40 Fe (111) oligatomic thin films (2.4≦D M≦9.4 atomic layers) at temperatures between 123 K and 373 K. A comparative discussion of the results is given. Anisotropies of the films, determined by both methods, agree roughly. Approximately, they show a 1/D M-dependence on the film thickness, as expected from an interpretation as surface anisotropy. FMR is shown to be a useful experimental tool for the investigation of oligatomic ferromagnetic films. Informations may be taken from the resonance field, line width, line shape and total absorbed microwave power. The magnetic moment must be taken from magnetometry.
