Crystallography of the Hexagonal Ferrites

Science, 1971
The hexagonal ferrites form an unusual group of complex, ferrimagnetic oxides embodying some 60 known crystal structures. These include phases for which the structural unit cell is larger than that in any known inorganic materials. The various hexagonal ferrite modifications fall into two distinct structural series, each formed by the ...

Magnetostriction of some hexagonal ferrites

Journal of Applied Physics, 1981
With the aim of beginning a systematic characterization of the magnetoelastic properties of the hexagonal ferrites we measured the room temperature magnetostriction in a number of these materials. The analysis of the experimental results allows us to conclude that: a) the saturation magnetostriction in hexaferrites is of the same order of magnitude as ...

Influence of Co4+-Ca2+ substitution on structural, microstructure, magnetic, electrical and impedance characteristics of M-type barium–strontium hexagonal ferrites

, 2020
Co4+-Ca2+ substituted M-type barium strontium hexagonal ferrites with chemical composition Ba0.25Sr0.75CoxCaxFe12-2xO19 (x = 0.0, 0.2, 0.4, 0.8, 1.2, 1.6 and 2.0) were prepared by sol-gel auto combustion technique and sintered at 1150 °C for 5 h.

Hexagonal Ferrites at Millimeter Wavelengths

9th European Microwave Conference, 1979, 1979
Hexagonal ferrites may show a renaissance as candidates for various microwave devices in the millimeter wavelength range if perfect and low-loss materials, either bulk crystals or epitaxial layers, can be grown. Use is made of the large anisotropy fields of compounds with uniaxial magnetic anisotropy. These intrinsic anisotropy fields together with the

Dielectric Properties of Hexagonal Ferrites

physica status solidi (a), 1986
Dielectric properties of hexagonal ferrites BaFe12O19, BaTi2Fe4O11, and BaSn2Fe4O11 are examined from 4.2 to 500 K. BaFe12O19 shows low dielectric constant and conductivity, while BaTi2Fe4O11 shows large dielectric constant and conductivity. On the other hand BaSn2Fe4O11 which has the same crystal structure as BaTi2Fe4O11 exhibits very low dielectric ...

New Mn-Substituted Hexagonal Ferrites

Journal of Applied Physics, 1965
Seven new hexagonal ferrite structures have been identified by single-crystal x-ray diffraction during a study of crystals from Mn-substituted Y phase syntheses. They fall in the M2Yn series and are comprised of a c-axis stacking of 2 five-anion-layer M blocks permuted with 9–13 six-anion-layer Y blocks.
