“…This effect is highly dependent on the morphology and particle size, as well as the alloy-epoxy ratio and solidification conditions, as well as the magnitude of the applied magnetic field. There are two main driving forces for the orientation of particles in a magnetic field, namely magneto crystalline anisotropy and shape anisotropy [96], therefore, under certain conditions (for example, Fe-Ga in the form of flakes with <111> in plane directions), the application of a magnetic field may not be effective in increasing magnetostriction. Another way to improve the functional properties of composites is to select particles of a certain size.…”

Fe-Ga is a promising magnetostrictive rare-earth free alloy with an attractive combination of useful properties. In this review, we consider this material through the lens of its potential use in magnetostrictive applications at elevated frequencies. The properties of the Fe-Ga alloy are compared with other popular magnetostrictive alloys. The two different approaches to reducing eddy current losses for such applications in the context of the Fe-Ga alloy, in particular, the fabrication of thin sheets and Fe-Ga/epoxy composites, are discussed. For the first time, the results of more than a decade of research aimed at developing each of these approaches are analyzed and summarized. The features of each approach, as well as the advantages and disadvantages, are outlined. In general, it has been shown that the Fe-Ga alloy is the most promising magnetostrictive material for use at elevated frequencies (up to 100 kHz) compared to analogs. However, for a wide practical application of the alloy, it is still necessary to solve several problems, which are described in this review.

“…In comparison with a static magnetic field (SMF) [16], strong magnetic field [17] and pulsed magneto-oscillation (PMO) [18] suggested method has few advantages: (1) an ability to control particles packaging density (from loose to dense structure); (2) possibility to provide core-coating process using the dynamic magnetic platform.…”

Soft magnetic composites (SMCs) of Fe3O4 particles coated with Al nanoparticles were prepared using the rotating magnetic field method, and the microwave absorption properties and microstructures of these composites were investigated. The results show that a well-distributed Al nanoparticles coating layer was formed on the surface of the Fe3O4 particles upon mechanical friction and rotating magnetic field distribution. Scanning electron microscopy SEM and X-ray diffraction XRD studies show that the rotating magnetic field method can produce a uniform coating of the aluminium layer on the Fe3O4 particles. Compared with common composites from Fe3O4 particles, SMCs of Fe3O4(Al) particles have stronger magnetic loss behaviour and weaker dielectric loss ability, as well as good reflection characteristics over a wide frequency range. The minimum reflection loss (RL) is −16.2 dB at 12.0 GHz for a corresponding thickness of 5 mm obtained for SMCs of Fe3O4(Al) particles. The presented rotating magnetic field method used in the Fe3O4 particles coating process with Al nanoparticles has great potential in composite materials synthesis with different morphology and areas of application.
