Influence of particle size and compaction pressure on the magnetic properties of iron-phenolic soft magnetic composites

Magnetization dynamics of FeCuNbSiB soft magnetic ribbons and derived powder cores

“…2. The real part of permeability strongly depends on the size of particles, density, number of pores, non-magnetic phase, crystal anisotropy and magnetic anisotropy [35].…”

Strategy to Enhance Magnetic Properties of Fe78Si9B13 Amorphous Powder Cores in the Industrial Condition

“…The µ e , however, increased first and then decreased. A small increment of 1.08 for µ e was observed as the mass ratio of P1%/P2%/P3% changed from 20:70:10 to 30:60:10, which could be attributed to the increase of the average particle size for AMPCs [29].…”

“…Within the content range of 0.5 wt.%-1.5 wt.%, the ρ increased with the increase of the sodium silicate content. This was due to the lubrication film on the particle surface, generated by the coating agent, which can enhance the mobility of the particles during the compacting process [27,29]. For the µ e , too low content of sodium silicate (0.5 wt.%, seen in Figure 6a) would result in the increased number of pores, due to the poor bonding effect for the particles in the AMPCs.…”

Magnetic multiresonance behavior of Fe@Al2O3 nanoembedments and microstructural evolution during mechanosynthesis

“…In particular, magnetic nanoembedments consisting of magnetic nanoparticles encapsulated by insulating hosts have attracted considerable attention owing to their wide range of applications, such as magnetic resonance imaging (MRI) [5], magnetic fluid [6], novel high frequency soft magnetic materials [7,8] and magnetic drug carriers [9]. Physical properties of such nanoembedments are influenced by their size, size distribution and volume fraction of the metal nanoparticles.…”
