Abstract Nanoparticles of formula Co 1- x Zn Fe 2 O 4 ( = 0.0, 0.3, and 0.5) were prepared successfully using a citrate-auto-combustion method. This work studies the substitution effect 2+ ion on physical, chemical, structural properties CoFe . The structure samples was determined via X-ray diffraction (XRD) Fourier transformed infrared spectrometer (FTIR). investigated ensures that all crystal...
