Magnetic Properties of Bi and Si Oxides-Doped M-Type Barium Ferrite

Cation distribution and intrinsic magnetic properties of Co-Ti-doped M-type barium ferrite

The structural and magnetic properties of BaFel, I z,cO,Ti~,Ois (0(x< 1.0) M-type barium ferrite have been investigated by means of neutron powder diffraction and high-field magnetization measurements. The cationic’distribution and magnetic moments of the five different metallic sublattices are determined and compared to the experimental saturation magnetization. It is found that about 50% of C...

M-Type Barium Hexagonal Ferrite Films

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...

Realization of hexagonal barium ferrite thick films on Si substrates

Hexagonal barium ferrite thick films (50–200μm) have been deposited on Si and Al2O3/Si substrates using a screen printing technique. X-ray diffractometry, scanning electron microscopy and magnetometry were used to characterize and correlate the ferrite films’ microstructure and magnetic properties. The experiments indicated that an Al2O3 underlayer was effective in preventing silicon diffusion ...

R-Ferrite-type barium cobalt stannate, BaCo2Sn4O11

BaCo(2)Sn(4)O(11) is isotypic with R-ferrite, BaTi(2)Fe(4)O(11). The Co atoms fully occupy trigonal-bipyramidal sites () and are disordered with Sn atoms in octa-hedral sites (.2/m symmetry), as represented in the formula BaCoSn(2)(Co(0.34)Sn(0.66))(4)O(11). Ba atoms are situated in a 12-fold coordinated site ( symmetry).
