Giant dielectric response, nonlinear characteristics, and humidity sensing properties of a novel perovskite: Na_1/3Sr_1/3Tb_1/3Cu₃Ti₄O₁₂.

ABSTRACT: In this study, we unveil a novel perovskite compound, Na_1/3Sr_1/3Tb_1/3Cu₃Ti₄O₁₂, synthesized through a solid-state reaction method, exhibiting remarkable giant dielectric response, nonlinear characteristics, and humidity sensing capabilities. This research highlights the emergence of a Cu-rich phase, the properties of which undergo significant alterations depending on the sintering conditions. The optimization of sintering parameters, encompassing a temperature range of 1040-1450 °C for 1-8 h, resulted in substantial dielectric permittivity (ε') values (∼2800-6000). The temperature dependence of ε' demonstrated relationship to the particular sintering conditions utilized. The acquired loss tangent values were si
