Chromium substituted Co‐Mg ferrite with composition Co0.5Mg0.5Cr0.4Fe1.6O4 has been synthesized by solgel auto combustion method. X‐ray diffraction technique confirmed the formation of cubic spinel structure with no additional phase. In order to distinguish the effect of crystallite size‐ induced broadening and strain‐ induced broadening of XRD peaks, Williamson and Hall analysis has been performed...
Dielectric properties such as dielectric constant (ϵ′) and dielectric loss tangent (tan δ) are reported for Cu substituted Ni‐Zn ferrite having formula Ni0.2Cu0.2Zn0.6Fe2O4 prepared by sol–gel auto combustion method. T he variation of dielectric constant, dielectric loss tangent and A. C. conductivity with frequency are measured in the frequency range 1000 Hz to 120 MHz at room temperature. the real...
