Ferrite with mixed complex oxides BiNaFe2O5, BiKFe2O5 was synthesized by high temperature solid state reaction. The structure of the ferrites, type of syngony, parameters of the unit cells, radiographic and pycnometric densities were determined by X-ray phase analysis for a first time: BiNaFe2O5 – а=5,577, с=13,86 Å, γ=120º, Vun.cell. = 373,9 Å3, Z=4, ρrad.= 7,5262 г/см3, ρpicn.=7,5271 г/см3, BiKFe2O5 –а=5,545, с=13,65 Å, γ=120º, Vun.cell.= 363,45Å3, Z=6, ρrad.= 8,0367, ρpicn.=8,0375 г/см3. A comparative analysis of the relationship between crystal lattice parameters with parameters of the crystal lattice of initial oxides and complex ferrites has been performed. Research dependence of the magnetic moment of the complex ferrite BiNaFe2O5 of the applied magnetic field at a constant temperature T = 6.1405 K showed a paramagnetic shift in the structure.
