<p>Spintronics, which merges principles of magnetism and electronics, has emerged as a transformative field with the potential to revolutionize data storage, logic devices, and quantum technologies. Metal oxide nanostructures synthesized via sol–gel techniques are particularly promising for spintronic applications due to their low-cost fabrication, tunable structures, and magnetic functionalities. This mini-review summarizes recent advances in sol–gel-derived magnetic metal oxides, including transition-metal-doped TiO₂, La_1−xSr_xMnO₃, Co-doped ZnO, and Fe₃O₄, focusing on their synthesis, structural control, and room-temperature ferromagnetism. The influence of the sol–gel process on dopant distribution, grain boundary effects, and defect-mediated magnetism is discussed in detail. Key spintronic properties such as magnetoresistance, spin polarization, and magnetodielectric behavior are highlighted, along with current challenges in reproducibility and phase purity. Finally, the review outlines future directions for integrating sol–gel-derived metal oxides into practical spintronic devices, aiming to connect sol–gel chemistry with condensed matter physics and provide guidance for researchers at the intersection of materials science and spintronics.</p><p></p>
