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 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 کاملEffect of Annealing Temperature on the Structural, Magnetic and Optical Properties of SrCo2Fe16O27 Hexaferrite Nanostructure
In this paper, W-type SrCo2Fe16O27 hexaferrite nanostructures were synthesized by sol-gel auto-combustion method. Effect of annealing temperature on the structural, magnetic and optical properties of these SrCo2Fe16O27 nanostructures was investigated. In order to determine the annealing temperature of samples, the prepared gel was examined by thermo-gravimetric and differential-thermal analyses...
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 کاملSwift heavy ion irradiation-induced modifications in structural, magnetic and electrical transport properties of epitaxial magnetite thin films
The effect of swift heavy ion SHI irradiation 190 MeV Ag on structural, electrical transport and magnetic properties of epitaxial magnetite Fe3O4 thin films thickness 70 nm grown on MgO 100 oriented substrate have been investigated. The x-ray diffraction shows that at low fluence values up to 5 1011 ions/cm2, the strain in the films is relaxed, whereas, at higher fluence range 1 1012–1 1013 ion...
