Barium hexaferrite suspensions for electrophoretic deposition

Journal of Colloid and Interface Science, 2009
In this investigation we have looked at the preparation of barium hexaferrite suspensions, with the stability of the magnetic barium hexaferrite particles being increased by the addition of a surfactant, dodecylbenzylsulfonic acid (DBSA). The influence of the solubility DBSA in different solvents and its adsorption onto the surfaces of particles with ...

Crystallization of barium hexaferrite

Proceedings, annual meeting, Electron Microscopy Society of America, 1992
Barium hexaferrite (BaFe12O19) is a promising candidate for high density magnetic recording media due to its superior magnetic properties. For particulate recording media, nano-sized single crystalline powders with a narrow size distribution are a primary application requirement.

Formation of barium hexaferrite

Journal of Magnetism and Magnetic Materials, 1975
Abstract The reactivity of hematite produced by pyrolysis of iron salts at various temperatures was assessed by surface area measurement, electron microscopy, crystal size and by reacting it with BaCO3 to form hexaferrite. The effect of heating rate, soaking temperature and time were studied.

Magnetoelectric Hexaferrites

Annual Review of Condensed Matter Physics, 2012
Magnetoelectric (ME) multiferroics are materials that combine coupled electric and magnetic dipoles. Studies of ME multiferroics are a time-honored research subject because of their potential for future electronic devices. Recent discoveries have revealed that ferroelectricity can be induced by complex internal arrangements of magnetic moments.

Formation of U-type hexaferrites

Journal of Materials Research, 2004
The formation of U-type hexaferrites with the composition Ba4B2Fe36O60 (B = Co, Ni, Zn) was studied. Samples were characterized by means of x-ray diffraction, electron microscopy (with energy-dispersive spectroscopy), and thermogravimetric and thermomagnetic analyses.
