Structure and magnetic properties of Co-Ni-Li ferrites synthesized by citrate precursor method

► Co0.5Ni0.5−2xLixFe2+xO4 (0.0≤x≤0.25 in steps of 0.05) were prepared by citrate precursor method. ► Structural, morphology and magnetic properties of the prepared samples were investigated. ► The effect of adding Li1+ ions in enhancing the magnetic properties of the samples were studied. ► All the result obtained from XRD data, FTIR spectra and VSM data reinforce each other. ► The PSA and TEM estimated data are in a good agreement and ensure the nanoscale of the particle sizes.
