Dry Pressing of Barium Ferrite in the Orienting Field

Spin 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...

M-Type Barium Hexagonal Ferrite Films

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).
