ROFeM（R=La，Nd; M=As，P）材料的结构性质、缺陷和结构相变
Structural properties, defects and structural phase transition in the ROFeM (R=La, Nd; M=As, P) materials
摘要：
利用电子衍射、高分辨透射电子显微镜（TEM）和原位冷却TEM观察分析了ROFeM（R=La，Nd; M=As，P）材料的结构特性。实验结果表明，层状ROFeM晶体通常含有各种结构缺陷，如堆垛层错和小角度边界。原位TEM研究表明，在150 K附近，伴随着显著的自旋密度波（SDW）不稳定性，在晶体对称性和局部微结构特征上都可以清楚地观察到复杂的结构转变。
英文摘要：
The structural properties of the ROFeM (R=La, Nd; M=As, P) materials have been analyzed by means of electron diffraction, high-resolution transmission-electron microscopy (TEM) and in-situ cooling TEM observations. The experimental results demonstrate that the layered ROFeM crystals often contain a variety of structural defects, such as stacking faults and small-angle boundaries. The in-situ TEM investigations reveal that, in association with the remarkable spin-density-wave (SDW) instability near 150 K, complex structural transitions can be clearly observed in both crystal symmetry and local microstructure features.
