Magnetic and microwave absorption properties of barium hexaferrite doped with La3+ and Gd3+
In this paper, BaLaxGdxFe12-2xO19 (x=0.2, 0.4, 0.6 and 0.8) were synthesized via sol-gel auto-combustion method. Fourier transform infrared spectroscopy (FTIR) of samples was represented that the bands at 400 and 500 cm-1 were related to the formation of hexaferrite phase. The (x-ray diffraction) XRD patterns were matched exactly with the structure of barium hexaferrite. (Field emission scanni...
متن کاملMagnetic 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 کاملStructural, Magnetic and Acetone Sensing Properties of Barium- Calcium Hexaferrite Synthesized by Sol- Gel Auto Combustion Method
In this research, barium calcium hexaferrite (Ba1-xCaxFe12O19 , 0≤x£1) nanoparticles were synthesized through a sol-gel combustion method. The dried gel samples were then calcined at 950ᵒC for 4:30h. The phase and microstructural evolution of calcined samples were investigated by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM), respectively. The results revealed formation ...
متن کاملCation distribution and intrinsic magnetic properties of Co-Ti-doped M-type barium ferrite
The structural and magnetic properties of BaFel, I z,cO,Ti~,Ois (0(x< 1.0) M-type barium ferrite have been investigated by means of neutron powder diffraction and high-field magnetization measurements. The cationic’distribution and magnetic moments of the five different metallic sublattices are determined and compared to the experimental saturation magnetization. It is found that about 50% of C...
متن کاملMagnetic and Structural Properties of Barium Hexaferrite BaFe12O19 from Various Growth Techniques
Barium hexaferrite powder samples with grains in the μm-range were obtained from solid-state sintering, and crystals with sizes up to 5 mm grown from PbO, Na₂CO₃, and BaB₂O₄ fluxes, respectively. Carbonate and borate fluxes provide the largest and structurally best crystals at significantly lower growth temperatures of 1533 K compared to flux-free synthesis (1623 K). The maximum synthesis tempe...
