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 کاملThermal annealing effect on the structural and magnetic properties of barium hexaferrite powders
Samples examined in this experimental work were in the form of hexagonal barium ferrite with various temperatures annealing. Barium hexaferrite (BaFe12O19), is of great importance as permanent magnets, particularly for magnetic recording as well as in microwave devices. The variation of the temperatures annealing was found to affect coercivity, mean effective anisotropy field, magnetic viscosit...
متن کاملStatic and dynamic magnetic properties of Co2Z barium ferrite nanoparticle composites
The static, dynamic and attenuation properties of Co2Z barium ferrites and Co2Z composites have been studied. The results showed that both static and dynamic magnetic properties are significantly different for large particles and nanoparticles. As compared to large particles, Co2Z nanoparticles have a small saturation magnetization Ms , large coercivity Hc , small permeability μ0 and μ ′′ max, ...
