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 ...

International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2020
In this paper, the design of a permanent magnet assisted synchronous reluctance motor (PMASynRM or PMASRM) is presented as a replacement for a suitable permanent magnet in a simulated synchronous reluctance motor (synrm).

Bonded ferrite-based exchange-coupled nanocomposite magnet produced by Warm compaction
Journal of Physics D: Applied Physics, 2020Many modern technologies require permanent magnets with combinations of properties that cannot be met by conventional metallic or ceramic magnets. Ferrite/polymer composite magnets are a type of rare-earth free magnet with a wide range of magnetic and ...

Magnetic Disaccommodation in Ferrous Zinc Ferrites
Physica Status Solidi (a), 1988Magnetic disaccommodation in the temperature range 80K≧T≧420K, is investigated for nonstoichiometric zinc ferrites (ZnxFe3-x-ΔO4) as a function of the nominal composition (0 ≦ × ≦ 0.5) and the oxygen partial pressure during sintering stage (10−2 atm ≦ PO2 ≦ 10−7atm), directly related to the vacancy content Δ.

Novel Metamaterial: Magnetized Ferrite - Wire Medium
2007 Loughborough Antennas and Propagation Conference, 2007Novel metamaterial, based on wire media embedded into magnetized ferrite, is proposed and studied. Magnetic bias field is parallel to the wires and a wave propagates transversely to this direction. In this case effective permeability can be introduced.

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.

Publisher Summary This chapter focuses on M-type ferrites, which with high coercivity are called hard ferrites. Ferrite magnets were first introduced commercially by Philips under the trade name Ferroxdure, the isotropic form being introduced in 1952 and the anisotropic form in 1954. The magnetoplumbite crystal structure is characterized by the space
