Development of a Stress Insensitive MgCuZn-NiCuZn Composite Ferrite Useful for Microinductors Applications

Ultra-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...

Influence of Small Addition of Ti4+ Ions on the Properties of High Permeability Ferrite

Mn-Zn ferrites substituted with Ti4+ ions are now becoming commercially important. The substitution with titanium ions in Mn-Zn ferrite is recommended for ferrites with low losses and low temperature factor of initial permeability, Tdpi because of the shift of the secondary maximum of permeability, SMP, towards lower temperatures [I] and the increase of he d.c.resistivity [3,4,5]. The present p...

Synthesis and Structural Characterization of Nickel Substituted Manganese Zinc Nanoferrites

Magnetic oxides are naturally occurring minerals. In order to understand their unique properties and their utilization in technological applications, one must fully understand the correlation between chemistry, structure, particle size and processing. Among the broad classification of magnetic oxides, the spinel ferrites gain much importance because of their low cost, high magnetic permeability...

TEMPERATURE AND FREQUENCY DEPENDENT PERMEABILITY OF SPINEL TYPE Li-Cd FERRITE

A series of Li-Cd ferrite samples of composition Li0.5-x/2CdxBi0.02Fe2.48-x/2O4 for x = 0.0 to 0.7 were prepared by conventional double sintering ceramic technique. From temperature dependent permeability, μ′ at T=TC indicates that the samples have high homogeneity according to Globus et al. The Curie temperature, TC is found to decrease with increasing Cd content. The sample with x=0.7 shows a...
