   The paper addresses the physical context of the permeability frequency spectra mechanism in Ni, NiZn ferrites and ferrite-polymer composites. Complex permeability spectra of the presented materials have been studied in a wide frequency range. The NiZn ferrite powder was mixed with PVC as a matrix to prepare magnetic dielectrics for application in various electronic devices owing to specific behaviour of their complex permeability and sufficiently high resistivity.

Keywords: ferrite, ferrite-polymers, complex permeability spectra, demagnetizing field
