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...

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 in transition-metal-doped gold clusters: M@Au6 (M = Ti, V, Cr).
The electronic structure and magnetic properties in a series of transition-metal-doped Au clusters, MAu6- (M = Ti, V, Cr), are investigated experimentally using photoelectron spectroscopy (PES) and density functional calculations. PES features due to the impurity atoms and the host are clearly observed. It is found that all the MAu6- and MAu6 clusters possess a planar structure, in which the tr...
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...
