This research examines the structural and magnetic properties of monodomain cobalt ferrite nanoparticles with formula (Co1−xFex)A[Fe2−xCox]BO4. The particles were synthesized using various methods, including coprecipitation (with without ultrasonic assistance), followed by mechanochemical treatment, microemulsion, microwave-assisted hydrothermal techniques. resulting materials extensively analyzed X-ray diffraction (XRD) measurements to investigate how different synthesis methods affect structure cation distribution in nanoscale CoFe2O4. For ranging from 15.8 19.0 nm size, coercivity showed a near-linear increase 302 Oe 1195 as particle size increased. Saturation magnetization values fell between 62.6 emu g−1 74.3 g−1, primarily influenced inversion coefficient x (0.58–0.85). XRD analysis revealed that larger Co2+ cations migrate B- A-sites (decreasing x), lattice constants inter-cation hopping distances increase, while average strength super-exchange interactions decreases. study establishes connection samples their features. Importantly, this demonstrates careful selection method can be used control these nanoparticles.
