SrFe12O19 В КАЧЕСТВЕ ПРИМЕСИ В ПЕРОВСКИТОПОДОБНЫХ ФЕРРИТАХ
2023A decrease of oxygen content in SrFe12O19 and its subsequent decomposition were studied by coulometric titration. The significant release of oxygen during stepwise decomposition can be considered as a specific characteristic of SrFe12O19.

Preparation and magnetization dynamics of CoFe2O4–SrFe12O19 nanocomposites
Journal of Materials Science: Materials in Electronics, 2019Composites of different weight ratios were prepared from CoFe2O4 and SrFe12O19 nanoparticles. The pure phase formation was confirmed by X-ray diffraction analysis. The average crystallite size of the individual CoFe2O4 and SrFe12O19 nanoparticles were found as 17 nm and 43 nm, respectively.

SrFe12O19/ZnO hybrid structures: Synthesis, characterization and properties
Journal of Alloys and Compounds, 2010Abstracts SrFe12O19/ZnO hybrid particles were synthesized by an in situ hydrolysis method, using zinc acetate as zinc source. X-ray diffraction (XRD), infrared spectra, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were utilized to characterize the prepared hybrid particles. The results confirmed that SrFe12O19 and ZnO

Magnetization reversal and interactions in SrFe12O19
2016Coercivity and interactions in coprecipitated and ceramic SrFe12O19 (Sr-M) hexaferrite samples were studied using remanence curves and magnetic viscosity in addition to microstructural considerations by means of SEM analysis. Following a magnetic viscosity formalism, the activation volume was obtained and interactions were evaluated using the M ...

ИССЛЕДОВАНИЕ ДЕФЕКТНОЙ СТРУКТУРЫ ПЕРОВСКИТОПОДОБНЫХ ФЕРРИТОВ, СОДЕРЖАЩИХ ПРИМЕСЬ SrFe12O19
2023A strong negative effect of SrFe12O19 impurity presence in perovskite-type ferrites on the results of the coulometric titration has been revealed. A method has been developed to deter-mine the amount of impurity and recover the oxygen content data in perovskite ferrites con-taminated with SrFe12O19.

Structure, texture and properties of SrFe12O19 magnets
2018Permanent magnets (PMs) play a key role in modern society, as they are indispensable in an enormous variety of applications.[1, 2] Hexaferrite magnets, while much weaker than the rare-earth PMs, account for 85% (by weight) of the global sales of all PMs.[1] In particular, the M-type ferrite SrFe12O19 is a widely used rare-earth free, low-cost ...
