| 520 | |b Magnetic - nonmagnetic (1+ t) Mg2+→Mg2++Ni2+ substituted can be made in well known spinel ferrites Fe2(1- t) Mg1+t TitO4, were prepared by the conventional solid - state reaction sintering technique at 1300 ˚C and investigated by X-ray powder diffraction spectroscopic technique using Xray Line Profile Fitting Program, Xfit-Koalarie, the recorded reflection planes proved that all the prepared samples have cubic single phase spinel structure which indexed to the Fd3m space group. The true lattice parameters are determined accurately using Nelson-Riley extrapolation function. The density and distance between magnetic ions for both octahedral sites and tetrahedral sites are discussed depending on the composition parameter. The lattice parameter were found to be decrease linearly with increasing nickel concentration, thus obeying Vegard’s law, this variation is assigned to the substitution process and the migration of the Fe+3 ions with relatively small radius (0.64Å) into the A-sites on expense of Mg2+ ions (0.66Å). The decrement of the hopping lengths is attributed to the substitution process and different in ionic radii which makes that magnetic ions Fe3+ and Ni+2 on B-sites and Fe3+ ions on A sites become closer to each other, whereas, the density increases may be attributed to the replacement process and the influence of the difference in atomic weight of cations. all that parameters are influenced by the nickel concentration and cation distribution, thus will have an important effect on fundamental magnetic and electric properties. | ||
