The gel to carbonate precipitate route has been used for the synthesis of Ni1-xZnxFe2O4 (x = 0, 0.25, 0.5 and 0.75) bulk inverse spinel ferrite powder samples. The optimal zinc (50%) substitution has shown the maximum saturation magnetic moment and resulted into the maximum magnetic loss tangent (tanδm) > -1.2 over the entire 2-10 GHz frequency range with an optimum value ~-1.75 at 6 GHz. Ni0.5...

In the paper the novel soft magnetic composite system is investigated. A ferrofluid emulsion studied demonstrates the strong magnetic properties which are atypical for commonly known emulsions. Interaction of ferrofluid emulsions with a magnetic field is considered. Structural transformations in these media, such as deformation of emulsion microdroplets and emulsion inversion, are studied. The ...

Living organisms often combine soft and hard anisotropic building blocks to fabricate composite materials with complex microstructures and outstanding mechanical properties. An optimum design and assembly of the anisotropic components reinforces the material in specific directions and sites to best accommodate multidirectional external loads. Here, we fabricate composite films with periodic mod...

FeSiB based soft magnetic flakes (SMFs; ϕ: 63-106 µm, t: 2-5 µm) coated with optimally thick (∼10 nm) SiO2 were fabricated as the potential material for pressed cores suitable use in power inductors operating beyond 10 MHz. Such thin SMFs produced by mechanical ball milling of commercially available (∼27 ribbons followed an optimized sol-gel coating presence a silane coupling agent. Milling hel...

The intensive production of various biomedical composites made from different biomaterials showed a huge volume of information on properties of composite materials for appropriate research field. The matrix of composite materials is very important but the reinforcement materials known as fillers play an important role for the final properties of biomedical composites like mechanical properties ...

magnesium is potentially useful for orthopedic and cardiovascular applications. magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. however, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. one of the ways to improve the corrosion rate is to compose it with ceramic...

Abstract The paper analyzes the influence of hard and soft admixture on functional properties multiferroic ceramic composites. Two composite materials via solid-state reaction route were obtained. PZT-type (with or admixture) selected as ferroelectric component (90%), nickel–zinc ferrite magnetic (10%). doping type (soft component) composites’ dielectric, ferroelectric, electromechanical, magne...
