Indexing comparison: Pn′ma′ (No. 2 in Fig. 4) on left versus Pnm′a′ (No. 3 in Fig. 4) on right. In both the vertical dashed lines are expected Bragg peaks for the indicated magnetic space group. The small peak at ∼16° 2θ is from a contaminating phase. LaMnO3 powder data from NIST BT1 diffractometer kindly obtained from Q. Huang. |
