The structural properties of RFeMO (R = La, Nd; M = As, P) materials were analyzed by transmission electron microscopy (TEM), revealing that the layered RFeMO crystals often contain a variety of structural defects, such as stacking faults and small-angle boundaries. In situ TEM observations revealed a remarkable spin density wave (SDW) instability near 150 K, and associated complex structural transitions can be clearly observed in both crystalline symmetry and local microstructural features.
