Magnetic properties of (Co40Fe40B20)X(SiO2)100-X nanogranular composite films, [(Co40Fe40B20)X(SiO2)100-X /a-Si:n multilayer films and layered (Co40Fe40B20)X(SiO2)100-X films with X ranging from 30 to 80 have been characterized by means of magnetic measurements and ferromagnetic resonance. Layer thickness was varied between 1.3 and 6 nm. Thermal decrease of (Co40Fe40B20)X(SiO2)100-X composite magnetization follows the T3/2 law. The spectrum of standing spin-wave has been detected in the perpendicular experiment configuration for films with the metal phase content above 48 vol. %. It is found that the Hr(n2) dependencies are non-linear. Such behavior is probably caused by the fluctuations of magnetic parameters (the magnetization and the ferromagnetic exchange coupling) in nanocomposite films. A comparison between the magnetic properties of (Co40Fe40B20)X(SiO2)100-X granular films and [(Co40Fe40B20)X(SiO2)100-X/a-Si:n multilayer films was carried out.
