The NPD patterns and Rietveld refinement profiles of LaCu₃Fe₄O₁₂ at (a) 300 K and (b) 425 K. The observed (circles), calculated (red line), and difference (blue line) patterns are shown. Green ticks show the positions of the Bragg reflections, and pink ticks in panel (a) show the positions of magnetic reflections from the G-type antiferromagnetic ordering of the B-site spins.^[31]
