“…Ранее нами было показано, что соединение Sr 2 FeMoO 6−δ , являясь половинным металлом, обладает рядом интересных особенностей [6][7][8][9], привлекательных в качестве технологических применений этого перспективного материала в спинтронике. SFMO при температурах ниже температуры Кюри (T c ∼ 420−430 K) имеет структуру двойного перовскита и в основном (однофазном) состоянии является ферримагнетиком с почти 100% степенью спиновой поляризации (P).…”

Powders of strontium ferromolybdate (Sr2FeMoO6-δ) with various degrees of superstructural ordering of iron and molybdenum cations (P = 67%; 81%; 89%) were studied by the ferromagnetic resonance method. These investigations have been carried out taking into account the available information on the structural, magnetic and resistive characteristics of the samples under study. As a result of the analysis of the ferromagnetic resonance spectra, it was concluded that the amplitude of the corresponding signals strongly depends on the magnitude of the superstructural ordering, increasing with its growth. The presence of maxima in the ferromagnetic resonance spectrum in the temperature range 350–370 K, which shift slightly to low temperatures with increasing P, confirms the existence of ferrimagnetic and antiferromagnetic states competing with each other in the region close to the Curie temperature.

“…Previously, we have shown that Sr 2 FeMoO 6−δ compound, being a half-metal, possesses a number of interesting features [6][7][8][9], which are attractive for technological applications of this promising material in spintronics. SFMO at temperatures below the Curie point (T c ∼ 420−430 K) has a structure of the double perovskite and in its ground (single-phase) state it is a ferrimagnetic substance with an almost 100% degree of spin polarization (P).…”

Nanosized particles SrMnO3 perovskite was prepared by using sol gel method. The sintering temperature was modified to 700, 1000 and 1200 °C within 6 hours. The effect of sintering in nanosized particles and structural were carefully investigated by using X-Ray Diffractometer (XRD) and Scanning Electron Microscopy (SEM). All the synthesized particles show orthorhombic structure with progression from amorphous phase on lower temperature to single phase on higher temperature of sintering. The crystallite size tends to be constant while the particle size is adjusted. The SrMnO3 grain size also modified to larger as the sintering temperature increase indicating that structure and behavior of the particles could be improved by modified sintering temperature.
