我们报告了使用基于管内粉末（铁扩散 PIT）方法的简单原位铁扩散工艺成功制造了具有高传输临界电流密度 Jc 的多芯和单芯 FeSe 线。七芯线材在 4.2 K 时表现出高达 1027 A/cm2 的输运 Jc。在线材样品中观察到超导转变温度 Tczero 在 10.5 K 处，比块状 FeSe 高约 2 K。 Fe扩散PIT方法适用于制备性能优越的二元FeSe超导体多芯线材。
We report successful fabrication of multi- and mono-core FeSe wires with high transport critical current density Jc using a simple in-situ Fe-diffusion process based on the powder-in-tube (Fe-diffusion PIT) method. The seven-core wire showed transport Jc of as high as 1027 A/cm2 at 4.2 K. The superconducting transition temperature Tczero 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.
