These studies demonstrate how doping can significantly alter multiple material properties simultaneously, providing a theoretical framework for understanding the stability and characteristics of these materials. This comprehensive approach is crucial for developing materials that meet specific application requirements. Moreover, these studies highlight the predictive power of first-principles methods in guiding experimental research, offering a thorough overview of how doping affects various material properties and providing valuable data for future research and applications. The doping of perovskite materials, such as CaTiO\({}_{3}\), with various elements has been extensively studied to modify their properties for different applications. The structure of doped perovskites can vary based on the dopant used. For instance, Cr-doped perovskite materials exhibit an orthorhombic symmetry similar to SmFeO\({}_{3}\)[24]. Doping with divalent and/or trivalent ions can introduce lattice distortions and oxygen vacancies in perovskites like BaTiO\({}_{3}\) or CaTiO\({}_{3}\)[25]. Cation-anion co-doping has been shown to enhance the photocatalytic performance of CaTiO\({}_{3}\) perovskites [26]. Doping with different elementscan lead to significant changes in the properties of perovskite materials. For example, Pr- and Eu-doped CaTiO\({}_{3}\) exhibit pronounced photoluminescence emissions, with optimal lanthanide concentrations affecting the intensity of the emissions [27]. Additionally, doping with elements like Rh and Ln in layered perovskite Ca\({}_{3}\)Ti\({}_{2}\)O\({}_{7}\) can enhance their photocatalytic activity under visible light irradiation [28]. The doping of calcium titanate with various impurities allows for the manipulation of the ionic and electronic structure, thereby affecting the electrical properties of the compounds [29]. Moreover, the doping of nanostructured CaTiO\({}_{3}\) has been found to increase strain and defects in the structure compared to the pure material, impacting its piezoelectric properties [30]. Doping with Fe in CaTiO\({}_{3}\) decreases the bandgap energy of the material [31]. Furthermore, doping can improve the conductivity of perovskites like YMn\({}_{1-x}\)Cr\({}_{x}\)O\({}_{3}\), enhancing their performance in applications such as oxygen evolution [32]. Despite the extensive research on doped perovskite materials, there remains a gap in our understanding of the specific effects of varying Cr contents in CaTi\({}_{1-x}\)Cr\({}_{x}\)O\({}_{3}\) on its magnetic moment and semiconducting properties. Addressing this gap is crucial for advancing the development of materials for spintronic applications, for which the control of both spin and charge is essential. This study aims to provide a detailed theoretical analysis using density functional theory (DFT) to evaluate how the substitution of Ti\({}^{4+}\) with Cr\({}^{4+}\) influences the effective magnetic moment and semiconducting gap of CaTi\({}_{1-x}\)Cr\({}_{x}\)O\({}_{3}\). By employing DFT, this research focuses on analyzing the electronic properties of the perovskite-like material CaTiO\({}_{3}\), particularly examining the effects of substituting Ti\({}^{4+}\) with the magnetic transition metal Cr\({}^{4+}\) across various ratios (x = 0.0, 0.25, 0.5, 0.75, 1.0). The interactions between electronic orbitals associated with Ti-O-Cr inter-octahedral bonds are investigated to understand the resulting changes in magnetic response and semiconductor character. Our calculations encompass the electronic density of states, a band structure analysis, and magnetic moment assessments, thereby providing a comprehensive understanding of how Cr doping affects the material. This integrated approach aims to elucidate the fundamental mechanisms driving the observed modifications in magnetic and electronic properties, contributing valuable insights for the design of materials suitable for spintronic applications.
