卤代PNNO的磁性及相变温度

Magnetism and Ferromagnetic Transition Temperature of X-Substituted PNNO

采用量子化学GAUSSIAN 92 UHF PM_3方法对卤素取代的PNNO进行研究,讨论它的磁性及电子结构,并用自旋波理论预测了其二聚物的磁性相变温度(T_c),与用同样方法得到的对位硝基取代的PNNO相变温度比较,发现卤代PNNO有更高的相变温度.

Magnetism and ferromagnetic transition temperature (Tc) of X - substituted PNNO have been investigated by using quantum chemical GAUSSIAN 92 UHF PM3 method and spin wave theory. Study of nitro group substituted PNNO (p - NPNN) showed that X - substituted PNNO has higher Tc than p - NPNN.
