我们在n型铁磁半导体（In，Fe）As中观察到了超导电流。为此，我们制备了S/F/S（S：超导体，F：铁磁体）结，它在1 K以下的临界电流超过1 μA时，结宽达到1 μm时表现出零电阻。超导邻近效应的长范围表明，诱导超导电性是由自旋三重态配对（In，Fe）As。
We observed supercurrent through an n-type ferromagnetic semiconductor (In, Fe) As. For the purpose we prepared S/F/S (S: superconductor, F: ferromagnet) junctions, which exhibited zero resistance up to 1 µm of junction width with critical current over 1 µA below 1 K. The long reach of the superconducting proximity effect suggests that the induced superconductivity is brought about by spin-triplet paring in (In, Fe) As.
