Mg–Zn ferrite is considered as one of the important materials with potential uses in many applications. In this work, samples of ferrite Mg(1-x)ZnxFe2O4 (where x=0.0, 0.2, 0.4, 0.6, 0.8 and 1) were synthesized by the sol–gel method for use in some hyperthermia applications. The composition and purity of the prepared samples hardly affected their properties. Therefore, the elemental concentration of these samples was measured by the X-ray fluorescence technique and thermal neutron activation analysis to check the quality of the prepared samples. The results of both methods were compared with each other and with the molecular ratios of the as-prepared samples. In addition, no existing elemental impurity, with considerable concentration, was measured. •Mg–Zn ferrite is considered as one of the important materials with potential uses in many applications.•Samples of ferrite Mg(1-x)ZnxFe2O4 (where x=0.0, 0.2, 0.4, 0.6, 0.8 and 1) were synthesized by sol-gel method to use in some hyperthermia applications.•The elemental concentration of these samples was measured by the x-ray fluorescence (XRF) technique.•Thermal neutron activation analysis (NAA) was used for determination of the Zn, Mg and Fe concentration.•The results of both methods were compared with each other and with molecular ratios of the as prepared samples.
