Strontium cobalt zinc bismuth ferrites with formula are provided in this study using

formula Sr0.5Co0.4Zn0.4BixFe2-xO4 at different variation of x= 0.0, 0.05, 0. 10, 0.15

synthesized by Micro-emulsion techniques. To check the physical characteristics of this

series (Sr0.5Co0.4Zn0.4BixFe2-xO4) of nano-ferrites using FTIR (Fourier Transformation of

infrared spectroscopy), UV-visible, X-ray diffraction and scanning electron microscope.

SEM and XRD analysis were used to examine the structure and morphology of manufactured nano-ferrites. The spectra of XRD demonstrated the production of a single-phase cubic spinel ferrite structure in the nanometer size range with no minor phase.

When extending metal-oxygen bonds at tetrahedral and octahedral sites, FTIR analysis showed two bands centered at 592 and 410 cm- 1. Using ultraviolet-DRS, we determined that band-gap range for the synthesised magnetic materials was between 2.42 and 2.32 eV.
