Temperature-dependent response of electrical properties for Ti⁴⁺ doped Li_0.35+y/2Zn_0.1Mn_0.1Ti_yFe_2.35−3y/2O₄ spinel ferrites

Lithium-based ferrites having compositional formula Li_0.35+y/2Zn_0.1Mn_0.1Ti_yFe_2.35−3y/2O₄ where y in the range of 0.00–0.75 with 0.15 step size were prepared by the solid-state route. The sample’s single-phase cubic spinel structure was discovered using XRD investigation. Additionally computed were the structural parameters such as density, porosity, crystallite size, and lattice constant. Energy dispersive X-ray was used to establish the sample’s elemental compositions while scanning electron microscopy was used to determine the sample’s microstructural information. The temperature response of d.c. resistivity (ρ_d.c.) behaviour was studied from temperature-dependent, transmission electron microscope was used to determine the particle size, shape and distribution. For these samples, the a.c. electrical conductivity (σ_a.c.) properties were also covered. The nyquist plot analysis revealed the conduction mechanisms and the semicircle curve obtained depicted the contribution of resistance from the ceramic samples. The report presents a systematic analysis and discussion of the acquired results.
