Coercivity mechanism of rare-earth free MnBi hard magnetic alloys

- Based Rare - Earth - Free Permanent - Magnet Alloys

This study presents the structural and magnetic properties of melt-spun , , and alloys. Appreciable permanent-magnet properties with a magnetocrystalline anisotropy of about 9.6–16.5 , a magnetic polarization –10.6 kG, and coercivities –3.0 kOe were obtained by varying the composition of these alloys. Structural analysis reveals that the positions of x-ray diffraction peaks of show good agreeme...

Synthesis and Characterization of High Coercivity Rare-earth Ion Doped

Influence of replacing Sr ions by rare-earth ions (RE) ions on the structural and magnetic properties of high coercivity (Hc) SrFe10Al2O19 hexaferrite have been investigated using X-ray diffraction, transmission electron microscopy, differential scanning calorimeter, and SQUID. A 73% increase in intrinsic coercivity is observed for Al doped SrFe10Al2O19 as compared to that of pure SrFe12O19. Th...
