Study of dielectric and ac impedance properties of Ti doped Mn ferrites

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

“…This hopping causes local displacements in the direction of external electric field. This, in turn, enhances their contribution to the space charge polarization thereby leading to an increase in the value of dielectric constant [23]. The dielectric constant of any material, in general, is due to dipolar, electronic, ionic and interfacial polarizations.…”

Role of Coupling Divalent and Tetravalent Metal Ions on the Elastic and Electric Properties of CoFe2O4 Ferrites Prepared by Sol–Gel Method

“…Polycrystalline ferrites are very good dielectric materials, and very high dielectric constants are useful in designing good microwave devices such as isolators and switches [1,2]. The dielectric properties of ferrites depend upon several factors including the method of preparation, chemical composition, grain structure or size, and amount and type of the additives [3].…”

AC conductivity and dielectric properties of, Zn1−Cu Cr0.8Fe1.2O4 spinel ferrites

“…It can be seen also that tan ı versus frequency sometimes shows maxima. These maxima of tan ı as a function of frequency in ferrites are attributed to the coincidence of the hopping frequency of electrons with the frequency of the externally applied field [23][24][25]. The high values of losses may be very important in some future applications that depend mainly on the thermal effect of the losses.…”
