The effect of nano- SiO2 on the magnetic and dielectric properties of lithium cadmium ferrite

Synthesis and characterization of nano-sized pure and Al-doped lithium ferrite having high value of dielectric constant

“…When the driving force of the grain boundary for each grain is homogeneous, the sintering mass attains a uniform crystallite size distribution. Rather more strength of the driving force depends upon the diffusivity of the individual grains, sintering temperature and porosity [22].…”

Electrical and magnetic properties of magnesium-substituted lithium ferrite

“…For lithium ferrite, the conduction by hoping mechanism taking place between Fe 2+ and Fe 3+ ions present on equivalent crystallographic sites in the structure of the ferrite is given as follow [20]: Fe 2+ , Fe 3+ + e À In this model, the electron transfer between adjacent octahedral sites in spinel lattice. Local displacement of electrons in the direction of applied electric field can be obtained that occur due to the displacement in determining the polarization of ferrite [21]. However, in lithium ferrite, there are no Fe 2+ ions.…”

Minimizing of power loss in Li–Cd ferrite by nickel substitution for power applications

“…In applications like memory core devices, where high saturation magnetization is essential, Cd substitution is desirable as it increases the saturation magnetization up to a certain level of substitution followed by a decrease. Many researchers have studied Li-Cd [1,17], Li-Zn [5,18] and Li-Ni [10,19] ferrite systems. However no report has been found in the literature on dielectric, and power loss studies of Li-Cd-Ni ferrites.…”
