Magnetic and structural properties of M-type barium hexaferrite prepared by co-precipitation
Stoichiometric and single-phase barium hexaferrite (BaM) has been synthesized by co-precipitation and an additional solid state preparative method using high-purity nitrates, oxides and carbonates of iron (III), barium (II) and ammonium hydroxide. The isochronally and isothermally measured permeability and magnetic loss tangents over 1MHz–1GHz in frequency remained moderately constant until a s...

متن کاملMagnetic Properties of Fe Doped, Co Doped, and Fe+Co Co-Doped ZnO
The structural, electronic and magnetic properties of Zn0.95Co0.05O, Zn0.95Fe0.05O and Zn0.90Fe0.05Co0.05O nanoparticles prepared by a sol-gel method are presented and discussed. Xray diffraction and optical analysis indicated that high spin Co ions substitute for the Zn ions in tetrahedral sites. Fe Mössbauer spectroscopy showed the presence of isolated paramagnetic Fe ions in both Fe doped an...
متن کاملEffect of Heat Treatment on Structural and Magnetic Properties of Nanocrystalline SrFe12O19 Hexaferrite synthesized by Co-Precipitation Method
Nanocrystalline strontium hexaferrite (SrFe12O19) powders have been successfully synthesized using the facile Co-precipitation method. The ferrite precursors were achieved from mixtures of strontium and ferric chloride in an aqueous medium without any surfactant and soft template. The as-received powders were calcined at 800 and 1000 ˚C for 2 hours in air. The final powders were characterized b...
متن کاملOrder-disorder and magnetic exchange interactions in substituted strontium hexaferrite SrAxFe12-xO19(A=Ga, In)
The unusual magnetic behavior of the 1% site in SrGa,Fe12-,Olg (8.3Cu<6.0) and SrInXFc,,_,XO,, (0.3~~~1.4) has been investigated by means of 57Fe Miissbauer spectroscopy at 298 IL The bifurcation of the 12.k MGssbauer subspectrum into 12k, and 12k2 components vf widely differing intensities has been confirmed for both Ga”+ and 18. The bifurcation is apparent at s values as low as 0.3, and the l...
