dc.descriptionWe demonstrate that Fe sheathed LaO0.9F0.1FeAs wires with Ti as a buffer layer were successfully fabricated by the powder-in-tube (PIT) method. Comparing to the common two-step vacuum quartz tube synthesis method, the PIT method is more convenient and safe for synthesizing the novel iron-based layered superconductors. Structural analysis by mean of x-ray diffraction shows that the main phase of LaO0.9F0.1FeAs was obtained by this synthesis method. The transition temperature of the LaO0.9F0.1FeAs wire is around 25 K. The micrograph shows a homogeneous microstructure with a grain size of 1-3 micrometers. The results suggest that the PIT process is promising in preparing high-quality iron-based layered superconductor wires.
