Аннотация: Nanogranular Co-SiO2, and Co-CaF2 films are investigated using ferromagnetic resonance and magnetic measurements. The spectrum of standing spin-wave has been registered in the perpendicular experiment configuration for all types of films with the magnetic granules content above 52 vol.%. The dependences of resonance fields H-r of sПоказать полностьюpin modes on the mode number squared H-r(n(2)) are non-linear. Such behavior is supposed to be the result of the fluctuations of magnetic parameters (the magnetization and the ferromagnetic exchange coupling) in nanocomposite films. A comparison between the magnetic properties of Co-SiO2 granular films and Co-CaF2 films is carried out. The surface anisotropy value K-s of Co-SiO2 films is evaluated from the surface resonance modes of spin-wave resonance spectra as 3.5 x 10(-4)
