La2MnNiO6

La2MnNiO6 is a double perovskite ceramic compound combining lanthanum, manganese, and nickel oxides, belonging to the class of mixed-valence transition metal oxides. This material is primarily investigated in research settings for energy conversion and storage applications, where its mixed magnetic and electronic properties make it a candidate for catalysis, solid oxide fuel cells, and magnetoresistive devices. Unlike conventional single-metal oxide semiconductors, the Mn-Ni coupling in this perovskite structure enables tunable electronic and magnetic behavior, though it remains largely in the experimental phase without widespread industrial deployment.
