Abstract
Cobalt ferrite nanoparticles, whose degree of crystallinity and particle size depends on the molar ratio of glycine to cobalt and iron nitrates, are produced by the glycine-nitrate combustion method. The highest values of the particles’ degree of crystallinity (94%) and size (77–79 nm) are observed in samples produced at a molar ratio of 0.84 of glycine to nitrates. The values of the coercive force and residual magnetization increased, together with the glycine to nitrate ratio: at 1.12, they reached 33.8 emu/g and 1350 Oe, respectively. The saturation magnetization attained the maximal value (80 emu/g) at the molar ratio of glycine to nitrates of 0.56.
