Investigation of structural, hysteresis and electromagnetic parameters for microwave absorption application in doped Ba–Sr hexagonal ferrites at X-band

Journal of Alloys and Compounds, 2019
M-type Ba0.5Sr0.5CoxLaxFe12-2xO19 hexagonal ferrite has been synthesized by the conventional ceramic method. X-ray diffraction analysis confirmed formation of M-type hexagonal structure while scanning electron microscopy analysis revealed a reduction in ...

Millimeter Resonance Isolators Utilizing Hexagonal Ferrites

IEEE Transactions on Microwave Theory and Techniques, 1963
Ferrimagnetic resonance isolators operating over waveguide bandwidths have been developed in K, V and Q bands using hexagonal ferrites. Preliminary results on similar isolators operating in M and W bands have also been obtained. The materials employed in these isolators are highly anisotropic uniaxial hexagonal compounds.

Liquid phase epitaxy of hexagonal ferrites

Materials Research Bulletin, 1975
Abstract Single crystal films of the hexagonal ferrite Zn 2 Y, having the chemical formula Ba 2 Zn 2 Fe 12 O 22 , were grown by the isothermal dipping method of liquid phase epitaxy using a PbOBaOB 2 O 3 flux. The substrates were flux-grown M-type hexagonal ferrite crystals having the chemical formula BaFe 12 O 19 .

Control of electromagnetic properties in substituted M-type hexagonal ferrites

Journal of Alloys and Compounds, 2018
Present paper describes systematic studies of the functional BaFe12-xDIxO19 (DI = Al3+, In3+ 0.1 ≤ x ≤ 1.2) solid solutions. Correlation between the fine atomic structure and intrasublattice Fe3+ - O2− - Fe3+ superexchange interactions were explained ...

Lithium insertion into hexagonal ferrites: BaFe12O19

Materials Research Bulletin, 1988
Abstract The electrochemical insertion of lithium in the M-type ferrite with formula BaFe 12 O 19 has been investigated. The galvanostatic discharge curves of the (−)Li/electrolyte/Li x BaFe 12 O 19 (+) cell show a quasi-linear voltage decrease from 3.1 V vs. Li Li + at x=0 to about 1.0 V vs.

Electron Probe Microanalysis of Zinc-Bearing Hexagonal Ferrites

Advances in X-ray Analysis, 1965
AbstractThe electron probe is shown to be an effective tool for the analysis of the series of ferrimagnetic oxides referred to as the hexagonal ferrites. This series of compounds) containing barium, Fe3+, and a divalent metal cation, is formed by an ordered stacking of basic structural units in varying ratios.

Subsidiary resonance in planar hexagonal ferrites

IEEE Transactions on Magnetics, 1970
Subsidiary-resonance phenomena in single-crystal Mn-ZnY have been theoretically and experimentally investigated. Using the general expression for the first-order instability, the threshold fields have been calculated for material parameters (anisotropy field, saturation magnetization) appropriate to Mn-ZnY.
