摘要：
The microwave permeability of laminated composites based on thin FeCoBSi films was under study. The level of permeability increased with increasing of the ferromagnetic inclusions in the laminates. The intrinsic permeability spectra of ferromagnetic inclusion are parametrically reconstructed. The obtained parameters of magnetic resonance were specially analyzed. To avoid the effect of eddy current and to obtain large-volume fractions of ferromagnetic constituent, laminates consisting of alternating FeCoBSi/SiO2 multi-layers and mylar substrates were also investigated. For the same volume fractions of ferromagnetic constituent (8.7%), laminates based on multi-layered films are found to possess higher values of permeability than those based on one-layered films.
