Magnetization of Manganese Ferrite
Journal of Applied Physics, 1963The magnetization of manganese ferrite has been measured at low temperatures on samples prepared at several values of oxygen pressure and temperature within the stability field of the material. The systematic variation observed which extends from 4.55 to 4.88 Bohr magnetons is correlated with the degree of oxidation (determined by weight gain and ...

Tuning the magnetism of ferrite nanoparticles
Journal of Magnetism and Magnetic Materials, 2016Abstract The importance of magnetic interactions within an individual nanoparticle or between adjacent ones is crucial not only for the macroscopic collective magnetic behavior but for the AC magnetic heating efficiency as well. On this concept, single-(MFe 2 O 4 where M=Fe, Co, Mn) and core–shell ferrite nanoparticles consisting of a magnetically ...

Magnetic and relaxometric properties of Mn ferrites
Journal of Physics D: Applied Physics, 2008"We present the magnetic properties and the H-1 nuclear magnetic resonance dispersion profiles of Mn-ferrites-based compounds, as possible novel contrast agents (CAs) for magnetic resonance imaging (MRI). The samples consist of nanoparticles (NPs) with the magnetic core made of Mn1+xFe2-xO4, obtained by the rapid decomposition of metalcarbonyl into a ...

ChemInform Abstract: Magnetic Structures of Substituted Ferrites
ChemInform, 1990In this paper the magnetic structures of various substituted ferrites are reviewed. Attention is focused on the more usual case of a local canted state. Several systems and detailed magnetic experiments are listed and discussed. Then experimental phase diagrams (tetrahedral-octahedral iron concentrations) are established to distinguish between ...

Reviews of Modern Physics, 1953
A brief discussion is given of the meaning of initial permeability, the principles of its measurement, and the nature of "dimensional resonance." In considering magnetic spectra containing only a single resonance, typical data on sintered ferrites and on finely divided ferrite powders are reviewed, and some of the theoretical interpretations previously

Magnetic Resonance in Ferrites
Proceedings of the IRE, 1956Ferromagnetic resonance in ferrites is reviewed. The concept of tensor permeability, the influence of magnetic anisotropy, demagnetizing fields, and damping mechanisms are discussed. Special consideration is given to coupled magnetic systems and the behavior in ferrites with compensation points.

Magnetic aftereffects in magnesium ferrites
IEEE Transactions on Magnetics, 2001We report a study of aftereffect processes in magnetite with magnesium substitutions. The study observed the processes by means of disaccommodation techniques. We have recorded the time evolution of the initial magnetic susceptibility after sample demagnetization of polycrystalline specimens with nominal composition Mg/sub x/Fe/sub 3-x/O/sub 4/, 0/spl ...

The Magnetic Structure of Cobalt Ferrite
Proceedings of the Physical Society, 1963The domain structure of a single crystal of cobalt ferrite has been examined where it intersects the (100) faces of the crystal. The crystal, in an `as-grown' condition, showed magnetic domain structures which were typical of a crystal possessing uniaxial magnetic anisotropy together with a new, unusual structure which may indicate the mechanism of the

Magnetization in Nickel Ferrite-Aluminates and Nickel Ferrite-Gallates
Physical Review, 1953Trivalent aluminum and trivalent gallium have been substituted for trivalent iron in nickel ferrite NiO\ifmmode\cdot\else\textperiodcentered\fi{}${\mathrm{Fe}}_{2}$${\mathrm{O}}_{3}$ to give the systems $\mathrm{NiO}\ifmmode\cdot\else\textperiodcentered\fi{}{\mathrm{Fe}}_{2\ensuremath{-}t}{\mathrm{Al}}_{t}{\mathrm{O}}_{3}$ and $\mathrm{NiO}\ifmmode ...
