An iron-deficient (Ni_{0.33}Zn_{0.67})_{1 + x}Fe_{2 - x}O_4 and stoichiometric Ni_{0.45}Zn_{0.55}Fe_2O_4 prepared by a wet method were studied using the Mössbauer spectroscopy and thermomagnetic measurements. For the iron-deficient sample the T_{C} is twice as large and the temperature coefficient of initial permeability is two orders of magnitude lower in comparison with the stoichiometric samples. The results are supplemented by the frequency dependence of the complex permeability.
