Samples of ferrites of the General formula NixZn1–xFe2O4 (where x = 0.25, 0.5) are synthesized by low-temperature biochemical methods using urea, glycine, acetic and citric acid as a complexing agent. Radio absorbing properties of Nickel-zinc ferrites were investigated by ferromagnetic resonance (FMR). The influence of the complexing agent on the value of specific radio absorption of synthesized samples is determined.
