Microstructure, electrical properties and Hall coefficient of europium-doped Li–Ni ferrites

Structural Analysis and Normalised Susceptibility Study of Zn Substituted Li-Cu Ferrite

“…reaction kinematics, atomic weight and radii of constituent ions [26]. Similar results are reported by S. A. Mazen et al [23] and Muthafar F. Al-Hilli [27]. S. Manjura et al [25] have reported the value of Dx in the range 4.6 gm/cc to 5.2 gm/cc for Li-Cu mixed ferrite and they synthesized the samples by the solid state reaction method and sintered at 1000˚C.…”

Dielectric relaxation, conductivity behaviour and magnetic properties of Mg substituted Ni–Li ferrites

“…Soibam et al have reported the high value of magnetization for Ni-Li-Zn ferrites [7]. The electrical properties of Li-Ni-Eu and Li-Mg-Ti ferrites have been reported by Al-Hilli et al [8] and by Bellad and Chougule [9], respectively. The properties of ferrites are also dependent on the method of synthesis [10].…”

Dielectric relaxation, conductivity behavior and magnetic properties of Mg substituted Zn–Li ferrites

“…The peak is observed when the hopping frequency of electrons between Fe 3þ and Fe 2þ is in resonance with the frequency of applied electric field i.e., maximum electric energy is transferred to the electrons and the loss shoots up at resonance [21]. The Debye equation for the loss tangent is tand ¼ ðe s À e u Þus tand e s þ e u ðus tand Þ 2 (8) where e s and e u are the dc and high-frequency dielectric constants, respectively, s tand is the relaxation time and u is the angular frequency of the applied field.
