“…Though diminishes significantly, weak absorption from these bands remain present after the heat treatment even at 800 C. The appearance, thermal stability and temperature dependence of these absorption bands in IR spectra of LaFeO 3 synthesized by other methods involving organic species is common. Examples include the LaFeO 3 synthesized by gel combustion [32,45,46], microwave assisted combustion [31], solid state reactions [47], solegel [20] and hot soap [26] methods.…”

“…The sample obtained at G/N = 1.2 despite on the smallest size of crystallites is excluded from consideration as it contains an only trace amount of LaFeO 3 . Thus, from a practical point of view, the lanthanum orthoferrite nanocrystals obtained at G/N = 1.0 are the most interesting since they have the smallest crystallite size and the narrowest crystallite size distribution among the whole set of samples, what meets important requirements for nanopowders using as a basis for magnetic and electric materials [4,5].…”

“…Lanthanum orthoferrite, due to its wide prevalence in comparison with other rare-earth elements (REE) and its particular property set, is the basis for many functional materials applied in catalysis, solid-oxide fuel cells, chemical sensors, magnetic and electrode devices etc. [2][3][4][5][6][7][8][9]. Lately, materials based on LaFeO 3 are also considered as promising materials to obtain hydrogen by the photocatalytic decomposition of water under visible light irradiation [10][11][12].…”

Varying glycine to nitrate ratio in the initial solution the powders based on nanocrystalline LaFeO 3 were synthesized by solution combustion synthesis. The powders were studied by X-ray diffractometry, scanning electron microscopy, adsorption analysis and helium pycnometry. The average crystallite size of the synthesized LaFeO 3 nanocrystals ranged from 18±2 to 85±9 nm, and the specific surface area of the nanopowders based on them ranged from 8 to 33 m 2 /g. Based on the results, the influence of redox composition of the reaction solution on the nature of the combustion processes, as well as the composition, structure and properties of LaFeO 3 nanocrystals were analyzed. Here, it wasshown, that the nanopowders have specific microstructure in terms of monocrystalline nanoscale layers of lanthanum orthoferrite, therefore it is allowed to consider them as a promising base for catalytically and magnetically functional materials.

“…Convergence in basis size is achieved with a cut-off RMT.Kmax = 8.0, which is product of smallest muffin-tin radius RMT times the largest plane wave vector Kmax. Brillouin zone (BZ) integration is done with 56 K point using modified form of tetrahedron method [17]. The calculations are self-consistently converged when total energy and charge is stable within 0.001mRy and 0.01 m respectively.…”
