AB  - Nanosize Li-ferrites were synthesised by the thermal decomposition of an appropriate mixture of complex compounds with acetylacetone - (2,4 pentadione) ligands ([M(AA)(x)]; M = Li and Fe) at 500 degrees C. The obtained sample is composed of three phases determined by the standard Rietveld procedure: Li0.5Fe2.5O4 (S. G. P4(3)32), Li1.16Fe3O4 (S.G. Fd (3) over barm) and LiFeO2 (S.G. Fm (3) over barm). Cation distribution in nanosize ordered spinel Li0.5Fe2.5O4 deviates from that of the bulk counterpart. Microstructure parameters (crystallite size of similar to 23 nm and strain of 3.2526(9) x 10(3)) were determined by the Rietveld refinement of the TCH-pV parameters. SEM microphotographs show a particle size of similar to 50-60 nm. An order disorder phase transition in ordered spinel Li0.5Fe2.5O4 was studied by DSC measurements and in situ XRPD technique. The temperature of phase transition was found to be 762 degrees C ( DSC) and (745 +/- 5) degrees C ( XRPD).

AB  - The ultrafine spinel NiFe1.9M0.1O4 powders (M=Al, Y, Cr, Fe) were synthesized by thermal decomposition of appropriate mixtures of complex compounds with acetylacetone - (2,4 pentadione) ligands ([M(AA)(x)]) at 500 degreesC. Samples were annealed in the temperature range 600-1000 degreesC and the crystallization process was followed by XRD. The largest crystallite size and the highest crystallization rate are observed for NiFe1.9Al0.1O4, while the opposite was found for NiFe1.9Y0.1O4. Strain value in NiFe1.9Y0.1O4 changes sign at temperatures between 700-800 degreesC, while for NiFe1.9M0.1O4 (M=Al, Cr) it has a positive sign and reaches the maximum value at 700 degreesC. The crystal structure of the Samples annealed at 1000 degreesC was refined using the Rietveld profile method. Cation substitution in Ni-ferrite changes its structural and microstructural parameters, and can also significantly influence other physical properties.

AB  - Solid solution (Fe1-xCrx)(H2O)(6)(NO3)(3)x3H(2)O was crystallized in different ratios of basic nitrates-nonahydrates of chromium and iron. The x-ray diffractometer method showed their structural isomorphism. Magnetic susceptibility measurements showed their paramagnetism. The dependence of molar susceptibility on concentration x is linear. The calculated magnetic moments for Cr and Fe are in good agreement with values taken from the literature.
