Abstract We address the detailed description of magnetic properties (001) and (111) interfaces between hard CoFe 2 O 4 (CFO) soft NiFe spinel ferrites, used in bicomponent systems for permanent magnet applications. The similarity electronic properties, order lattice structure both oxides allows us to isolate effect ideal interface formation on magnetism combined system based density functional ...

Some spinel ferrites, MFe2O4 (M = Cu, Cd and Zn), having submicron grain sizes (0.1–0.7μm) were prepared by sol-gel-selfcombustion and their sensing properties to reducing gases were investigated. The gas sensing characteristics were obtained by measuring the sensitivity as a function of various controlling factors, like operating temperature, composition and concentration of the gas, and final...

Mixed Mg-Mn ferrites of compositions Mg0.9 Mn0.1 Inx Fe2-x O4 and Mg0.9 Mn0.1 Aly Fe2-y O4 have been synthesized by the citrate precursor technique. The X-ray diffraction patterns of the samples confirmed the formation of single-phase spinel structure. The ferrites have been investigated for their electric and dielectric properties. The dc resistivity and Curie temperature were found to be incr...

— The influence of the Zn and Cd ion contents upon the natural spin resonance in Ni-Zn and Ni-Cd ferrites has been investigated. Previous experiments by other authors have shown that substituting Zn ions for Ni ions leads to a change of the total effective anisotropy field and consequently of the natural spin resonance frequency fi. ft measurements have been carried out by using a coaxial line ...

Microwave ferrites require high coercivity for their use as microwave absorbers. Strontium hexaferrite is one of the best material due to its magnetic properties , high coercivity, large unilateral magnetic anisotropy and very low cost in comparison to others make it suitable for the use as microwave components specifically microwave absorber .Strontium nano hexa ferrites were successfully synt...

In this research, electroplated magnetically isotropic and anisotropic soft alloys and screen-printed soft ferrites applicable to micromachined micromagnetic devices are fabricated and characterized using in situ measurement techniques. Appropriate magnetic materials and deposition methods, such as electroplating and screen-printing techniques, are examined and material test structures are fabr...

Samples of Ba1.266Ti2.956 Fe7.6Li0.844O19 hexaferrite have been prepared using anatase and rutile phases of TiO2 by classical ceramic route. A pure sample of Ba Fe12O19 has also been prepared for comparison. The structural, electrical and magnetic characteristics have been studied by XRD, SEM, FTIR, two probe method, hysteresis loop and susceptibility curves. The samples exhibit hexagonal magne...

This review focuses on cadmium ferrites numerous doped versions' production methodologies, characterization, applications. The structural, electric, magnetic, dielectric properties are prima...

A series of Cr substituted Mg-ferrites were synthesized by coprecipitation technique annealed at 900 o C for 6h. XRD analysis technique was used to confirm the formation of synthesized ferrites structure and the particle size estimated by Scherrer formula was found to be lying in the range 42.4 to 84.8 nm. All the prepared samples exhibited inverse cubic spinel structure and lattice parameter f...
