Synthesis, structure and substitution mechanism of manganese Mn doped barium hexaferrite BaFe12-xMnxO19

Results in Chemistry
Polycrystalline BaFe12-xMnxO19 samples (x = 0–2, step 0.5) were synthesized by the ceramic technique. The dopant content in the ceramics was controlled by its charge content.
