Thermal 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 کاملStructural and Magnetic Properties of Nanosized Barium Hexaferrite Powders Obtained by Microemulsion Technique
Thin hexagonal barium hexaferrite particles synthesized using the microemulsion technique were studied. A water-in-oil reverse microemulsion system with cetyltrimethylammonium bromide (CTAB) as a cationic surfactant, n-butanol as a co-surfactant, n-hexanol as a continuous oil phase, and an aqueous phase were used. The microstructural and magnetic properties were investigated. The particles obta...
متن کاملMagnetic and structural characterization of nanosized BaCo_xZn_2-xFe_16O_27 hexaferrite in the vicinity of spin reorientation transition
Numerous applications of hexagonal ferrites are related to their easy axis or easy plane magnetocrystalline anisotropy configurations. Certain W-type ferrites undergo spin reorientation transitions (SRT) between different anisotropy states on magnetic field or temperature variation. The transition point can be tuned by modifying the chemical composition, which suggests a potential application o...
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 کاملEffect of fuel content on structural and magnetic properties of solution combusted Mn0.8Zn0.2Fe2O4 powders
Single phase Mn0.8Zn0.2Fe2O4 powders were synthesized by solution combustion method. The solution combustion method relies on the exothermic self-sustained reactions in reactive solution containing of oxidizers and organic fuels. In this work, the effects of various amounts of glycine as fuel on the powder characteristics were investigated. The structure, cation distribution, microstructure, ma...
