Exchange-Coupling Behavior in SrFe12O19/La0.7Sr0.3MnO3 Nanocomposites [PDF]
Ceramics, 2019 Magnetically hard-soft (100-x) SrFe12O19-x wt % La0.7Sr0.3MnO3 nanocomposites were synthesized via a one-pot auto-combustion technique using nitrate salts followed by heat treatment in air at 950 °C. X-ray diffraction (XRD), transmission electron microscopy (TEM), and vibrating sample magnetometry (VSM) were used to characterize the structural and ...

In situ crystallization and magnetic measurement of hexaferrite glass-ceramics
AIP Advances, 2021 Glass-ceramic (GC) materials have the formability advantages of glasses and the opportunity for controlled crystallization of functional ceramic phases. Here, we obtain GCs containing the hard magnetic phase Sr-hexaferrite (SrFe12O19) from a borate glass.

Hydrothermal Synthesis of SrFe12O19 and Its Characterization
Journal of Superconductivity and Novel Magnetism, 2012 We have synthesized strontium hexaferrite particles in an alkaline medium using a hydrothermal process at 180 °C. Crystalline phase of samples were determined by XRD and spectroscopic, morphological, and magnetic investigation of the sample were FT-IR, SEM, and TG analysis, respectively.
