Frequency Variation of Complex Permeability in Dual Ferrite Filler — Single Polymeric Matrix Composites
نویسنده
چکیده
The frequency dependences of complex initial permeability for triplecomponent composite materials based on two different types of ferrite filler (MnZn and NiZn ferrite) and a nonmagnetic polymeric matrix (PVC) were studied in the frequency range of 10 kHz–1 GHz. The frequency dispersion of permeability is discussed by means of a dynamic model based on the superposition of the two types of magnetic resonance, the resonance of vibrating domain walls and the resonance of precessing magnetic moments in domains.

متن کاملUltra-low percolation threshold in ferrite-metal cofired ceramics brings both high permeability and high permittivity
High permeability and high permittivity are hard to be achieved simultaneously, either in single-phased materials or in composite materials, such as ferrite-ferroelectric ceramic composites and ferrite-metal percolative composites. In this work, ultra-low percolation threshold is achieved in NiZnCu ferrite-Ag cofired ceramics, which endows the composite with both high permeability and high perm...
