Spin Reorientation in Substituted Barium Ferrite
Résumé
The structural transformation of substituted hexagonal ferrite powders BaFe10CoTiO19 prepared by mechanical milling, was investigated as a function of grinding time by means of Mössbauer 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.
