abstract = {The structural properties of cobalt ferrite nanoparticles
have significant effects on their magnetic behavior. In the
current study, we thoroughly scrutinized and optimized the
structural characteristics of CoFe$_2$O$_4$ nanoparticles
and the correlation with their magnetic properties as a
function of the synthesis parameters using Rietveld
structure refinement. Nanoparticles were synthesized using
co-precipitation method based on design of experiments and
then characterized using X-ray diffraction, vibrating sample
magnetometry, transmission electron microscopy, and energy
dispersive X-ray spectroscopy analyses.Based on response
surface methodology studies, we identified factors that had
an effect on the structural and magnetic features. In order
to reach maximum magnetization, the cations distribution was
optimized, and the pH amount and reaction temperature were
identified as the most influential factors.We observed that
the initial cation ratio of Co$^{2+}$/Fe$^{3+}$ sharply
affected the cations distribution, which was subsequently
involved in the different structural characteristics and
magnetization of nanoparticles. Thiscan be attributed to the
hybrid structure formation and magnetic exchange
interactions of cations. Finally, the maximum magnetization
was achieved at the optimum cations distribution of
(Co$_{0.32}$Fe$_{0.68}$)(Co$_{0.70}$Fe$_{1.30}$)O$_4$, where
the difference between distributed cobalt cations in
tetrahedral and octahedral sites was minimum.},
