title: Determination of concentrations of Fe, Mg, and Zn in some ferrite samples using neutron activation analysis and X-ray fluorescence techniques.
abstract: 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.
