XRD patterns for the powder samples of (a) Ce-45 MMP, (b) Ce-27 MMP, and (c) Ce-27 SMP sintered magnets. The black dots show the observed experimental data and the red full line represents the calculated fits to the experimental data. Green line shows the difference between the fitted and observed results. The Bragg positions of RE₂Fe₁₄B, REFe₂, and RE-rich phases are indicated by vertical bars in blue, red, and olive, respectively.^[6]
