Magnetic properties of Be or Cu-substituted NiZn ferrites

Contribution to analysis of Cu-substituted NiZn ferrites

“…M s was found to increase with increasing concentration of substituent x up to a certain value. Similar behaviour was published in [4]. Our measured data can be qualitatively compared to well-known behaviour of the saturation magnetic moments of mixed Ni 1Ày Zn y ferrites as a function of zinc concentration y [5], which was measured at 4.2 K, see Fig.…”

Structural, electrical and magnetic properties of Cu1−xZnxFe2O4 ferrites (0≤x≤1)

“…Both of them increase up to x = 0.2 and then decrease with the increase in Zn concentration. Simi- lar reports about saturation magnetization have been quoted by others [26][27][28]. The increasing trend suggests that the variation in magnetic properties can be explained on the basis of Néel two sub-lattice model [29].…”

Ferrite multiphase/carbon nanotube composites sintered by microwave sintering and spark plasma sintering

“…They explained that the high density of a soft magnetic material is beneficial to its magnetic properties for a high saturation magnetization. 22), 24) So the improvement of the saturation magnetization should be partially associated with the density increasing. When the grain size is larger than the singledomain size, the magnetocrystalline anisotropy of local regions within the grains cannot be decreased distinctly with the coupling effect of ferromagnetic exchange between the grains.…”
