Influence of MoO3 and V2O5 co-doping on the magnetic properties and microstructure of a Ni–Zn ferrite

Evolution of double magnetic resonance behavior and electromagnetic properties of flake carbonyl iron and multi-walled carbon nanotubes filled epoxy-silicone

“…Therefore, it is reasonable that the exchange resonance frequency of FCI particle/MWCNTs filled polymer shifted to lower frequency as the FCI content increased, when taken into account the exchange interactions and shape anisotropy in such composites. Such result is also quite consistent with the results of other studies, which have clearly highlighted the particles shape and interface affected the exchange resonance of the composite materials [35][36][37]. MWCNTs and different FCI particles content (from 0 to 50wt%) based on the transmission line theory.…”

Complex permeability and permittivity spectra of polycrystalline Ni–Zn ferrite samples with different microstructures

“…Ni-Zn ferrites have high potential for use in several electromagnetic devices operating in the radiofrequency region, since they have frequency-dependent physical properties, such as permittivity and permeability [1][2][3][4][5][6]. Generally speaking, extrinsic properties such as the permeability and permittivity spectra of polycrystalline ferrites are mainly determined by their composition and microstructure.…”

Effects of Co-substitution on wide temperature ranging characteristic of electromagnetic properties in MnZn ferrites

“…MnZn ferrites are widely used as core materials for transformers in switching mode power supplies (SMPS) and DC/DC converters [1][2][3][4][5]. The anisotropy compensation is an important concept in manufacturing these materials.…”
