摘要: We used nano-channel alumina (NCA) and a sol-gel process to prepare La0.6Nd0.2Na0.2MnO3 nanowires . The morphology and crystal structure was be characterized by field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM). And transmission electron microscopy shows that the diameters of nanowires are around 30 nm. The low dc field magnetic response measurement was carried out by superconducting quantum interference device (SQUID). And the result shows that the Curie temperature of La0.6Nd0.2Na0.2MnO3 nanowire is about 155K,is less than the Curie temperature of bulk.The result may due to the size effect and the surface effect or the distorsion of the magnetic domain.
