Abstract

Two samples of combustion synthesized nickel ferrite nanoparticles were characterized using X-ray diffraction, scanning and transmission electron microscopy, magnetization measurements and Mössbauer spectroscopy with a high velocity resolution. It was shown that Mössbauer spectra of nickel ferrite can be well fitted by using ten magnetic sextets related to the different numbers of Ni²⁺ cations in the Fe³⁺ local microenvironments in both tetrahedral and octahedral sites supported by calculations of such probabilities. It was shown that increase of the number of Ni²⁺ cations in the ⁵⁷Fe local microenvironment around both sites leads to decrease of the hyperfine field.
