on the magnetic properties of fine

Magnetic Properties - Chemistry LibreTexts

This means the compound shows permanent magnetic properties rather than exhibiting them only in the presence of an external magnetic field (Figure (PageIndex{1})). In a ferromagnetic element, electrons of atoms are grouped into domains in which each domain has the same charge. In the presence of a magnetic field, these domains line up so that charges are parallel throughout the entire

Magnetic properties of electroless fine Co-P

Abstract: The magnetic properties (such as the saturation magnetization, the exchange stiffness constant, the local magnetic anisotropy field, the ferromagnetic resonance linewidth) of fine Co-P particles with different phosphorus concentration and particle sizes have been studied. The powders have been prepared by chemical reduction. The particle size was in the range of 0.1-3 /spl mu/m.

Size dependent magnetic properties of zinc

We investigate the particle size dependence of magnetic properties of ZnFe 2 O 4 fine particles. The fine particles with different particle sizes were obtained by heating the coprecipitated powder. The magnetization slowly increases with decreasing the particle size, and drastically in the particles with diameter < 30 nm. The size dependent magnetization shows maximum around ∼8 nm in
