AB  - In this work single phase hexagonal YMnO3 powders were prepared starting from Y(CH3COO)(3)center dot xH(2)O, Mn(CH3COO)(2)center dot 4H(2)O, KMnO4 and KOH using methods of conventional (280 degrees C for 6 h) or microwave assisted hydrothermal synthesis (200 degrees C for 2 h) followed by calcination at 1200 degrees C for 2 h. According to FESEM analysis the calcined powders consisted of submicronic YMnO3 particles, which were uniform in shape and size. Ceramic samples were obtained by sintering the as-synthesized powders at 1400 degrees C for 2 h. XRD analysis confirmed the presence of the single phase hexagonal YMnO3. SEM analysis showed a dense and homogeneous microstructure with typical inter- and intra-grain cracks. Magnetic measurements indicated ferrimagnetic properties that were explained by non-stoichiometry of the obtained compound and an excess of manganese that was confirmed by ICP analysis.

AB  - We have studied the formation of BiMnO3 (BMO) nanocrystalline perovskite powder produced by high-energy milling of the constituent oxides. The crystal structure and the amount of crystalline and amorphous phases in the powder as a function of the milling time were determined with XRPD using Rietveld refinement. BMO perovskite formed directly from highly activated nano-sized constituent oxides after 240 min of milling and subsequently grew during prolonged milling. The morphology, structure, and chemical composition of the powder were investigated by SEM and TEM. A clear ferromagnetic transition was observed at T (C) similar to 66 K for a sample milled for 240 min and increased with milling time. The magnetic hysteresis behavior is similar to that of a soft ferromagnet. The magnetic properties of the obtained BMO powders were found to change as a function of milling time in a manner consistent with variations in the nanocomposite microstructure.

AB  - Substituted lanthanum manganites with the general formula A(1-x) B (x) MnO3 (A = La, B = Ca, SraEuro broken vertical bar) have attracted a lot of attention due to their exceptional electric and magnetic properties. In this work, pure and Ca2+, Sr2+-doped LaMnO3 (LMO) with the concentrations of dopants 30% Ca2+ (LCMO), 30% Sr2+ (LSMO) and 15% Ca2+ + 15% Sr2+ (LCSMO) (in mol. %) were synthesized by polymerizable complex method. Bulk samples were prepared by sintering at 1300 A degrees C for 4 h in oxygen atmosphere. It was found that sintering in oxygen atmosphere enables preparation of single phase ceramics with rhombohedral crystal structure. Chemically prepared fine, submicronic precursor powders provided uniform microstructure and grain size distribution in final ceramics. As a result, pure and doped LMO ceramics with excellent microstructural and magnetic properties were obtained. Depending on the composition, magnetic measurements showed high saturation magnetizations (up to 93 emu/g), with values of the Curie temperature in the range 180-390 K and magnetoresistance up to 67%.

AB  - In this work, pure and Ca2+ and Sr2+ doped LaMnO3 powders were obtained using polymerisable complex method from citrate precursors. La2O3, Mn(NO3)(2) and citric acid were used for citrate formation, and ethylene glycol was later added as polymerisation agent. For the preparation of doped samples, solutions of Ca(CH3COO)(2) and Sr(NO3)(2) were used. Calcination was performed at 800 degrees C for 6 h in oxygen atmosphere. X-ray diffraction analysis showed that single phase LaMnO3, La0.7Ca0.3MnO3, La0.7Sr0.3MnO3 and La0.7Ca0.15Sr0.15MnO3 powders were obtained. Morphology of prepared samples was analysed using SEM analysis. Field cooled and zero field cooled magnetisations versus temperature and hysteresis loops of powders and sintered samples were analysed. Curie temperatures were in the range from 170 to 370 K, depending on composition. Measured magnetisations even reached 85 emu g(-1). The influence of dopants on magnetisation, Curie temperature and hysteresis loops were quantified and discussed.
