<p>This research work makes use of the chemical bath deposition (CBD) technique to create thin films of BaZr_xTi_1-xO₃ (<i>x</i> = 0.0 to 0.12). Alternatively, the experimental data is correlated with theoretical values using the BAND tool in the Amsterdam density functional (ADF) package. The temperature of the bath containing the 1.2&#xa0;M solution was kept at 78&#xa0;°C. When thin films are deposited in their as-deposited state, they exhibit amorphous behavior. However, when thin films are annealed at a temperature of 300&#xa0;°C, they exhibit a BaTiO₃ tetragonal Perovskite phase at <i>x</i> = 0.0 through 0.06, and phase change is detected at <i>x</i> = 0.08. At <i>x</i> = 0.08 to 0.12, the tetragonal phase of pure perovskite is seen in thin films of barium zirconate titanate (BZT). After annealing at 300&#xa0;°C, a transmission of around ~ 84% with an optical direct band gap of 3.55&#xa0;eV is determined for <i>x</i> = 0.12. We find that the experimental band gap values agree well with the theoretically obtained results. For <i>x</i> = 0.0 to 0.12, thin films of BaZr_xTi_1-xO₃ exhibit normal-anomalous dielectric behavior. At <i>x</i> = 0.12, the dielectric constant is at its highest and the tangent loss is at its lowest. The largest values of spontaneous and remnant polarization are observed in samples with <i>x</i> = 0.12. Mixed para-ferromagnetic behavior is seen by thin films of BaZr_xTi_1-xO₃ when <i>x</i> = 0. Alternatively, at <i>x</i> = 0.08–0.12, we see soft ferromagnetic behavior. Based on these results, CBD-grown BZT thin films have adjustable structural, dielectric, optical and magnetic characteristics, which bodes well for future multifunctional multipurpose electronic devices.</p>
