摘要：

We report successful fabrication of multi- and mono-core FeSe wires with high transport critical current density J(c) using a simple in-situ Fe-diffusion process based on the powder-in-tube (Fe-diffusion PIT) method. The seven-core wire showed transport J(c) of as high as 1027 A/cm(2) at 4.2 K. The superconducting transition temperature T-c(zero) was observed at 10.5 K in the wire-samples, which is about 2 K higher than that of bulk FeSe. The Fe-diffusion PIT method is suitable for fabricating multi-core wires of the binary FeSe superconductors with superior properties. (C) 2012 American Institute of Physics.
