Abstract
Reduction of freshly precipitated mixed hydroxides with hydrazine in strongly alkaline medium yielded nanostructured (5-20 nm crystallites) powders of the Fe-Co-Ni system in the entire region of compositions. They had different magnetic characteristics and were promising for the use as magnetic materials. The correlation between magnetic properties and phase composition, and also crystallite (species) sizes was explored. The reached values of saturation magnetization of samples in the region of an iron rich solid solution exceeded parameters of the known literature analogues. It was also found that dependencies, such as lattice parameter and composition for face-centered and cubic body-centered cubic phases of solid solutions were described by the flat surface equation.
