High Energy Ferrite Magnets [PDF]
Le Journal de Physique IV, 1997 Lanthanum and zinc substitution in M-type hexaferrite was studied in detail in order to increase the saturation magnetization. For the composition Sr0.7La0.3Fe11.7Zn0.3O19, the saturation magnetization was increased by more than 4% and the uniaxial anisotropy constant (K 1) was almost the same as that of non-substituted Ba-ferrite.

Magnetic Losses in Soft Ferrites
Magnetochemistry, 2022 We review the basic phenomenology of magnetic losses from DC to 1 GHz in commercial and laboratory-prepared soft ferrites considering recent concepts regarding their physical interpretation. This is based, on the one hand, on the identification of the contributions to the magnetization process provided by spin rotations and domain walls and, on the ...

Magnetic Studies on LiZn Ferrite Films [PDF]
Le Journal de Physique IV, 1997 In this paper, we report the study of the magnetic properties of (Li0.5-x/2 Mn0.1ZnxFe2.35-x/2O4) films with x=0, 0.16, 0.32, 0.48. The films were deposited on fused quartz substrates by rf sputteriug technique under various deposition conditions. The magnetic properties of the films annealed at 750°C are being reported.

Giant coercivity of dense nanostructured spark plasma sintered barium hexaferrite
, 2011 Due to the limited rare-earth elements resources, ferrite magnets need to be improved drastically. Ideally, for a true hard magnet, the coercive field should be larger than the saturation magnetization, which is not yet realized for ferrites.
