Аннотация: Magnetic properties of (Co40Fe40B20) X(SiO2)100-Xnanogranular composite films, [(Co 40Fe40B20)X(SiO2) 100-X/a-Si:H]n multilayer films and layered (Co40Fe 40B20)X(SiO2)100-Xfilms 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 (Co40Fe40B 20)X(SiO2)100-Xcomposite 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 H r(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 (Co40Fe40B 20)X(SiO2)100-Xgranular films and [(Co40Fe40B20)X(SiO 2)100-X/a-Si:H]n multilayer films was carried out. © (2012) Trans Tech Publications.
