Wiring systems powered by highly efficient superconductors have long been a dream of scientists, but researchers have faced practical challenges such as finding flexible materials. Here we report superconductivity in Nb2PdxS5-δ fibers with transition temperature up to 7.43 K, which have typical diameters of 0.3-3 μm. Superconductivity occurs in a wide range of Pd (0.6 < x <1) and S (0 < δ <0.61) contents, suggesting that the superconductivity in this system is very robust. Long fibers with suitable size provide a new route to high-power transmission cables and electronic devices.
由高效超导体供电的布线系统一直是科学家们的梦想，但研究人员面临着寻找柔性材料等实际挑战。在这里，我们报告了具有高达 7.43 K 的转变温度的 Nb2PdxS5-δ 纤维中的超导性，其典型直径为 0.3-3 μm。在广泛的 Pd（0.6<x<1）和 S（0<δ<0.61）含量范围内存在超导性，这表明该系统中的超导性非常稳定。具有合适尺寸的长纤维为高功率传输电缆和电子设备提供了新途径。
