15 صفحه اولSpin Reorientation in Substituted Barium Ferrite
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 mechan...

Structural, Electrical, and impedance spectroscopy studies of Barium substituted nano calcium ferrites synthesized by solution combustion method.
Barium substituted nanocrystalline ferrites with chemical composition BaxCa1-xFe2O4 (x =0.0 to 0.25) BCAF were prepared by solution combustion method. The phase formation of mixed spinal structured ferrites was confirmed by PXRD analysis. The average crystallite size was calculated using Debye-Scherrer formula and it was found to be in the range of 27-44 nm. Surface morphology was analyzed by S...
