The mean free path describes the average separation of boundaries between ferrite grains or crystals, regardless of the morphology of the ferrite, and it has been measured in the present work as the mean linear intercept length between boundaries. This quantity has been determined in an attempt ...
In order to design a low-cost high temperature ferrite alloy, the effects of carbon, and titanium on its solidification structure and properties have been studied. When the carbon content is increased from 0.07 to 0.35 wt%, the alloy grains becomes finer, and the grain boundaries become wider...
When such a material is cooled in an oxygen atmosphere, it is possible to form films of high resistivity over the constituent grains. Such a ferrite, in which the individual high-conducting grains are separated by either air gaps or low conducting layers, behaves as an inhomogeneous dielectric ...
摘要: Structure and dielectric properties of cobalt ferrite–hafnia are evaluated.Hf-incorporation significantly influences the properties of cobalt ferrite.Dielectric properties of the composites can be tailored by tuning Hf-content.关键词: Experimental/ cobalt compounds composite materials dielectric ...
The M-type hexaferrites come under hard ferrite category. The general chemical formula of M-type hexaferrite can be written as MFe12O19 (M = divalent elements like Ba, Sr, Pb, Zn, Mg, Ni etc.) which is like the magnetoplumbite structure2. Due to prominent electrical, magnetic, ...
Ferroelectric materials are characterized by the spontaneous polarization switchable by the applied fields, which can act as a “gate” to control various properties of ferroelectric/insulator interfaces. Here we review the recent studies on the modulati
This specific ferrite has a strong magnetocrystalline anisotropy and a high coercive field as a result of its atomic structure. The strontium hexaferrite is of special importance since it has drawn the attention of numerous researchers due to its unique electromagnetic behavior and applicability in a...
Structural, Magnetic, and Dielectric properties of Sr4Fe6O13ferrite prepared of small crystallites ArticleOpen access18 March 2020 Introduction Spinel structures are a group of compounds that are isotypes of crystalline spinel (MFe2O4), where M is a divalent cation. Due to their usefulness as ...
Despite many dedicated efforts, a highly efficient and accurate method for the synthesis of ferrite nanostructures is far from being achieved. On top, the correlation among the compositions, cationic distribution in the structure, electric and magnetic properties of ferrite nanostructures has not been ...
The magnetic-domain structure was investigated by using magnetic force microscopy. The magnetic-domain-length scale is 100-300 nm and 200-500 nm for Sm2Fe14.5Cu0.5Ga2C1.5and Sm2Fe15Ga2C1.0ribbons, respectively. Due to interactions between the grains, these values are larger than the grain ...
