Abstract
Ferrites with the general formula Li0.5Ni0.75−x/2Cdx/2Fe2O4 (where x = 0, 0.1, 0.3, 0.5, 0.7 and 0.9) were prepared by the standard double sintering ceramic method. X-ray diffraction analysis confirmed the single phase spinel structure of the samples. The variation of saturation magnetization (Ms) was studied as a function of Cd content. The dielectric constant (ε') and dielectric loss tangent (tanδ) were measured at room temperature as a function of frequency in the range 100 Hz–1 MHz. These parameters decrease with increasing frequency for all of the samples. The compositional variation of ε' and ρDC show an inverse trend of variation with each other.
