“…Basing on the Stoner-Wohlfarth (S-W) model the remanence-to-saturation (M R {M S ) ratio was estimated for various nanomaterials [11]. As it is well known the M R {M S dependence is dependent on the particles/crystallites size and shape as well as on the variation of anisotropy induced by an external magnetic field.…”

The paper is focused on the magnetic and structural properties of RCo5 (R = Y, Gd, Sm) intermetallics fabricated by high energy ball -milling (HEBM). The investigated samples were first produced by arc-melting as bulk materials and then were milled for 1h in dimethylformamide with balls to powder ratio 10:1. The influence of the HEBM parameters on the microstructure was investigated by a variety of complementary measurement methods. The Rietveld refinement was performed to estimate the dependence of crystallite size and microstrain on type of sample. The hysteresis loops were recorded by SQUID magnetometer at 2 K and 300 K and at magnetic field up to µ0H 7 T. The impact of short HEBM process is visible as the enhancement of coercivity and simultaneous reduction of the saturation magnetization.

“…Without surfactant, the produced particles are isotropic microparticles with equiaxed shape. Surfactants play an important role in the formation of such high aspect ratio submicron flakes [5][6][7][8][9][10][11][12][13]. Well dispersive and magnetically anisotropic particles could be aligned by magnetic fields and could be used to prepared anisotropic bonded magnets.…”

Across the most industry, the demand for nanoparticles is increasing. Therefore, many studies have been carried out to synthesize nanoparticles using various methods. The aim of this paper is to introduce an industryapplicable as well as financially and environmentally effective solution plasma process. The solution plasma process involves fewer chemicals than the traditional kit, and can be used to replace many of the chemical agents employed in previous synthesis of nanoparticles into plasma. In this study, this process is compared to the wet-reaction process that has thus far been widely used in the most industry. Furthermore, the solution plasma process has been classified into four different types (in-solution, out of solution, direct type, and remote type), according to its plasma occurrence position and plasma types. Thus, the source of radicals, nanoparticle synthesis, and modification methods are explained for each design. Lastly, unlike nanoparticles with hydrophilic functional groups that are made inside the solution, a nanoparticle synthesis and modification method to create a hydrophobic functional group is also proposed.
