Evidence of existence of metastable SrFe12O19 nanoparticles
(Elsevier Science, 2011-12)
The existence of metastable hexaferrite is reported. Synthesis of strontium hexaferrite, SrFe12O19, at 400 °C was realized under controlled oxygen atmosphere. Such technique allows obtaining of SrFe12O19 at lower temperatures ...
Magnetic properties of BaFe12O19 prepared by an ICR technique

Corrosion of steel alloys with ferrite coating
(2015)
The corrosion protection offered by coatings of hexagonal Sr ferrites on steel samples in the presence of chloride was evaluated by electrochemical techniques. Different samples were prepared using Nd-Co doped and un-doped ...
Light absorption properties of mesoporous barium hexaferrite, BaFe12O19
(Elsevier, 2019)
Light absorption properties are one of the most important characteristics of semiconductor materials,
since it is related to particle size, electric resistance, powder density, and dielectric constant. Barium hexaferrite ...
