Multiferroid properties of hexagonal barium ferrites

Russian Journal of Inorganic Chemistry, 2016
Samples of BaFe12O19 with high multiferroid properties at room temperature (maximum polarization P m = 48.0–9.5 μQ/cm2, residual polarization P r = 28.0–29.5 μQ/cm2, and electric coercive field Е c = 115–120 kV/m) have been obtained for the first time using ...

Morphological features of hexagonal ferrites

Materials Research Bulletin, 1967
Abstract Depression growth spirals and vicinal-hill type spirals have been discovered on basal faces of single crystal hexagonal ferrite samples. Electron microscopy studies have resolved sub-unit-cell etch steps on “process etched” and on HCl etched surfaces.

Aligned Co2Z Hexagonal Ferrite Fibers

Additional Conferences (Device Packaging, HiTEC, HiTEN, and CICMT), 2013
The hexagonal ferrites, also know as hexaferrites, have become massively important materials commercially and technologically, accounting for the bulk of the total magnetic materials manufactured globally, and they have a multitude of uses and applications. They all have a magnetocrystalline anisotropy; that is the induced magnetization has a preferred

Hexagonal ferrites for bubble domain devices

Materials Research Bulletin, 1970
Abstract Large crystals of aluminum substituted magneto-plumbite have been grown from a PbO·PbF 2 ·B 2 O 3 flux. Such materials may be used in bubble domain logic and memory devices. Quality is good for crystals grown with the c-axis horizontal at the bottom of the container while employing a negative vertical temperature gradient.

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 .

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.
