| dc.description.resumo | We report a theoretical study of the ferromagnetic resonance (FMR) frequency Ω(H) of Fe/FeF2(110) and Fe/MnF2(110) uniaxial anisotropy compensated bilayers. We show that under external field perpendicular to the anisotropy axis, the uniform mode of the Fe-film becomes soft at an external field strength (H∗=HFA−H⊥int) smaller than the Fe anisotropy field. For strong interface exchange coupling, there is a gap in the FMR spectrum. In this case, Ω(H) is a monotonically increasing function of the external field strength and for any value of the external field strength Ω(H)>Ω(0). The value of the effective interface field downshifts (H⊥int) and the value of Ω(0) may be used to estimate the interface exchange energy. | pt_BR |
