A double perovskite material, La2NiMnO6 (LNMO) shows remarkable ferromagnetic properties as well as semiconducting properties which makes it a promising candidate material for applications such as spintronics, catalysis, energy storage devices and many more. In this review, we present an in-depth characterization of the structural, magnetic, and electronic properties of LNMO using x-ray diffraction (XRD), Raman spectroscopy, vibrating sample magnetometry (VSM) and others. Monoclinic (P21/n) structural studies and near-room-temperature ferromagnetic ordering subject to antistites ordering are highlighted by magnetic analyses. Doping studies utilize elements such as Sr and Ba to also emphasize the tunable electronic characteristics of the material, for instance bandgap tunability for photovoltaic and dielectric purpose. The multifunctionality of LNMO is evidenced by practical implementations in oxygen evolution catalysis, supercapacitors and spintronic devices. These results highlight the importance of accurate characterization methods in enabling the continued advances in double perovskite materials for next-generation technologies.
