FeSiAl soft magnetic composites with NiZn ferrite coating produced via solvothermal method

Morphing soft magnetic composites.

Magnet filler-polymer matrix composites (Magpol) are an emerging class of morphing materials. Applications of Magpol can include artificial muscles, drug delivery, adaptive optics and self healing structures. Advantages of Magpol include remote contactless actuation, several actuation modes, high actuation strain and strain rate, self-sensing and quick response. The actuation modes of Magpol, i...

Complex permeability of soft magnetic ferrite/polyester resin composites at frequencies above 1 MHz

Composite soft magnetic materials consist of magnetic particles in a non-magnetic matrix. The properties of such materials can be modelled using effective medium theory. Measurements have been made of the complex permeability of composites produced using ferrite powder and polyester resin. The success of various effective medium expressions in predicting the variation of complex permeability wi...

Synthesis and magnetic investigation of cobalt ferrite nanoparticles prepared via a simple chemical precipitation method

In this research cobalt ferrite (CoFe2O4) nano-crystalline powders were prepared by simple chemical precipitation method using cobalt sulfate. The CoFe2O4 nanoparticles were characterized by X-ray diffraction, scanning electron microscopy  and Fourier transform infra-red spectroscopy. The crystallite size of CoFe2O4 nanoparticles was calculated by Debye–Scherrer formula. The effect of precursor...

Magnetic and Electrical Properties of Nanocrystalline Fe85Si10Ni5/Phenolic Resin Soft Magnetic Composites

In this work, nanocrystalline Fe85Si10Ni5 soft magnetic powders were prepared by mechanical alloying and subsequent annealing to reduce the internal stresses and lattice strains. The powders were mixed with phenolic resin and warm pressed to produce nanostructured soft magnetic composites. The effect of annealing time and temperature on the crystalline structure, microstructure and magnetic pro...
