(a) Temperature dependent x-ray diffraction of LaMn₃Cr₄O₁₂. Diffraction peaks were indexed based on space group Im-3. Stars show the diffraction peaks originating from a small amount of Cr₂O₃ impurity. (b)–(e) The enlarged views for several representative diffraction peaks. No structural phase transition occurs as temperature decreases from 293 K to 23 K.
