Abstract

The ferromagnetic Li 0 . l0 CU 0 . lO Nio. 30 Zno. 4o Fe 2.1 O 4 synthesized by the typical ceramic technique which is sintered at the various temperatures. The formation of single phase cubic spinel structure at varied sintering temperatures (T s ) is confirmed by the x-ray diffraction (XRD) analysis. XRD pattern confirms that the T s does not distress the inner structure of the sample. The bulk density and theoretical density are found to be improved with T s . Due to increasing of T s, a normal fast grain growth happens over the pores volume which reduced the porosity with sample density. The value of relative quality factor (RQF) and initial permeability are also enhanced with T s because of low porosity and high density. The peaks of the relative quality factor are shifted toward to the left with the T s which indicates the decreasing trend of the loss factor. The characteristics of structural, density, porosity, relative quality factor, initial permeability and loss factor of the composition are explained here.
