چکیده

The structural transformation of substituted hexagonal ferrite powders BaFetoCoTiO~s prepared by mechanical milling, was investigated as a fimction of grinding time by means of MOssbauer spectrometry and static magnetic measurements. A spin reorientation is clearly evidenced from the temperature dependence of the hyperfine parameters and of the initial magnetic permeability on the powder mechanically treated-for 23h.

Magnetic 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...

The Effects of Hydrogen Reduction on Magnetic Properties of Barium Ferrite Particles

A reduction process of the substituted Ba-ferrite has been found to be devided into three steps. At the first and second steps, the magneto-plumbite structure maintains and the coercivity increases. When the reduced-substituted Ba-ferrite particles are reoxidized, the coercivity is reversible in the first step but irreversible in the second step. During the third step, the magneto-plumbite stru...

Mössbauer spectra of CoZn-substituted Z-type barium ferrite Ba3Co2−xZnxFe24O41

Mössbauer spectra of powder and aligned Ba3Co2−xZnxFe24O41 samples with x=0–2.0 have been obtained and analyzed at room temperature and at T=7 K with applied magnetic fields of 0 and 60 kOe. The relationship between Mössbauer parameters and magnetic properties has been studied. The magnetocrystalline anisotropy of Ba3Co2−xZnxFe24O41 is modified from the c plane to the c axis at Zn concentration...
