Exploring the Multifunctional Properties of (Sr, Ni)‐Co‐Doped BaTiO3: Structural Characterization and Electromagnetic Characteristics
Year: 2024
Type: article
Abstract: The structural and electromagnetic properties of various Ba1-x(Sr0.5Ni0.5)xTiO3 were extensively investigated. XRD and Rietveld refinement were used to perform a structural study. With doping substances, bulk, and theoretical density decrease. The crystallite size was calculated using Scherrer and Williamson-Hall analysis. The microstructural properties were examined using images from FESEM. The observed values of dielectric constants are found to be in agreement with the porosity-corrected dielectric constants. The non-linear modified Debye equation (NLMDE) displays a reasonable goodness of fit value for the first five samples. A small polaron hopping mechanism may be responsible for the frequency-dependent ac conductivity observed in all samples confirming the Jonscher power law (JPL) fitted model. It was discovered that permeability initially increased and then decreased with doping substances. Initial permeability, experimental data from the M-H curve, and law-ofapproach-to-saturation (LAS) techniques show that Ba0.85(Sr0.5Ni0.5)0.15TiO3 and Ba0.75(Sr0.5Ni0.5)0.25TiO3 ceramics have electromagnetic properties. These ceramics are useful for fabricating electromagnetic sensors.
