Description
Summary:This study explores the synthesis and characterization of Fe-doped CaTiO 3 compounds via the Pechini method, focusing on their structural, magnetic, and electrical properties. Notably, a previously unreported magnetic property is observed in the Fe-doped CaTiO 3 compound. Despite significant structural distortions, ferroelectric polarization is identified using the Geometrical Polarization Approach (GPA), indicating its emergent nature. These distortions are attributed to robust chemical bonds between ionic O 1 −2 and Ti +4 sites, as evidenced by electronic density maps. This research sheds light on the potential of these materials for various technological applications.
