Rietveld refinement of step-scanned XRD patterns of [(Pr, Nd)1−x(La, Ce)x]2.14Fe14B powders for (a) x = 0, (b) x = 0.1, (c) x = 0.3, (d) x = 0.4 and (e) x = 0.5 at room temperature. Experimental pattern, calculated pattern and their differences are given in black, red and blue colors, respectively. Bottom ticks mark the characteristic Bragg positions of RE2Fe14B, Nd, REFe2 and Fe phases and serve as a guide to the eye.
