 Abstract
Nickel substituted nano-sized ferrite powders, , and (), were fabricated using a sol-gel method, and their crystallographic and magnetic properties were subsequently compared. The lattice constants decreased as quantity of nickel substitution increased, while the particle size decreased in ferrite but increased for the and ferrites. For the and () ferrite powders, the spectra could be fitted as the superposition of two Zeeman sextets due to the tetrahedral and octahedral sites of the ions. However, the spectrum of consisted of two Zeeman sextets and one single quadrupole doublet due to the ferrimagnetic and paramagnetic behavior. The area ratio of the spectra could be used to determine the cation distribution equation, and we also explain the variation in the parameters by using this cation distribution equation, the superexchange interaction and the particle size. The saturation magnetization decreased in the and ferrites but increased in the ferrite with nickel substitution. The coercivity decreased in the and ferrites but increased in the ferrite with nickel substitution. These variations could thus be explained by using the site distribution equations, particle sizes and spin magnetic moments of the substituted ions.
