Abstract
As a new approach of melt-injection-decomposition method, it has been successfully adopted for the synthesis of the complex oxides La0.67Sr0.33MnO3 nanowire arrays. X-ray diffraction studies confirmed the formation of perovskite manganite phase of the sample. Transmission electron microscope and scanning electron microscope characterizations showed a large quantity of one-dimensional nanowires is obtained and the nanowires are continuous, concrete, oriented and rather uniform with an average diameter of 170nm and length of several tens of micrometers. Magnetic measurements exhibited good ferromagnetic properties at the temperature of 10K and 300K respectively. The transition temperature of the complex oxides La0.67Sr0.33MnO3 nanowire arrays is about 350K, which will endow their great potential applications in magnetoresistance, spintronics or sensor fields at room temperature.
